Review: After reading the previous comments, I'm just glad that I wasn't the only person left confused, especially by the last 20 minutes. John Carradine is shown twice walking down into a grave and pulling the lid shut after him. I anxiously awaited some kind of explanation for this odd behavior...naturally I assumed he had something to do with the evil goings-on at the house, but since he got killed off by the first rising corpse (hereafter referred to as Zombie #1), these scenes made absolutely no sense. Please, if someone out there knows why Carradine kept climbing down into graves -- let the rest of us in on it!! All the action is confined to the last 20 minutes so I'll attempt a synopsis. John Carradine comes out to the cemetery to investigate, and is throttled by Zombie #1. So far, so good. But then we get the confusing scene where John Ireland and Jerry Strickler, out for a little moonlight filming in the graveyard, discover Carradine's dead body. Strickler repeatedly tries to push Ireland into the open grave from whence Zombie #1 had emerged, but Ireland succeeds in flipping him into the open grave instead, and PRESTO! Strickler comes out as Zombie #2! Yeah, I guess we can infer that Strickler was dead all-along (a witch?), but why he changed from normal appearance into rotting-flesh version by flying into Zombie #1's grave is never explained. (Considering how excruciatingly slow-moving these zombies are, I'd of thought he would have preferred to stay in his "normal" form until his business was concluded). This scene also brings a question to mind -- just who the heck IS Zombie #1 ??? We can only assume Zombie #1 is one of the original murder victims shown during the movie's opening credits, but who knows which one, nor why he has a particular grudge against the film crew.Anyway, after Ireland sees this transformation and runs away, we see the EXACT SAME SHOT of Zombie #2 shambling through the trees as we saw for Zombie #1. (This leads to momentary confusion over just how MANY zombies there really are). Then in best 1950's horror-movie fashion Ireland manages to trip while fleeing. He conveniently knocks his head on the small headstone of Faith Domergue's dead cat (wasn't that nice of John Carradine to chisel a tombstone for a cat that he barely knew?)Meanwhile, Zombie #1 has been wrecking havoc up at the house. He easily dispatches three film-crew members, then starts up the stairs. Faith Domergue hears him, and thinking it's lover John Ireland back from his night-shoot, goes out. Upon seeing it's only Zombie #1, she lets out a scream and retreats into a bedroom where she retrieves Ireland's revolver. While starlet Carole Wells is showering at this point and can't hear the scream, her co-star Charles Macauley (who's boozing and hamming it up at a mirror in his bedroom) does. Taking his sweet time (and only after some more swigs from his hip-flask) he finally decides to investigate. (One thing that strikes the viewer during the last quarter of this movie is how SLOW TO REACT the stars are to screams and gunshots). Domergue comes back out into the hallway armed and ready, but mistakes Macauley for Zombie #1 and shoots him six times! He does a nice acrobatic flip over the railing, then a horrified Domergue backs up, right into the waiting arms of Zombie #1.Carole Wells is by now out of her shower and drying off when she hears gunshots and Domergue's screams; she too feels no great urgency in running out to investigate. So during this time Zombie #1 has time to string Domergue up from the neck with a rope. Wells sees Domergue's hanging corpse and faints dead-away. The next time we see her is in a stream outside the house (???) -- but more on that later. Meantime, Ireland has recovered his senses and stumbles into the house where he discovers Zombie #1's bloody carnage. Though Ireland has just stumbled upon 3 murdered people he's more concerned that his film has been exposed and ruined! Mercifully for him (and the audience), Zombie #1 throws some movie equipment down on his head from the 2nd floor. That's the last we see of Zombie #1. At this point the audience is treated to a montage of all the deaths, showing that the new ones "mirror" the old ones. How profound.Zombie #2, meanwhile, has gotten near the house (remember, these zombies move as slow as molasses in January) where he happens to see Carole Wells floating by in a stream, and fishes her out. How did she get there? Did Zombie #1 carry her down, throw her in, then zoom back upstairs just in time to crush John Ireland? Apparently one of the original victims was drowned in the tub, so Wells has to drown too (but why outside in a stream, instead of in the tub, is never explained). Zombie #2 never makes it into the house himself (everyone's dead by now, anyways, thanks to Zombie #1) but instead he carries Carol Wells back to the graveyard. As the end credits flash on screen, we see Zombie #2 with his dead love still in his arms, descending into the open grave.The viewer is left wondering: Yes, but wasn't this Zombie #1's grave? Why is Zombie #2 taking up residence? And what if Zombie #1 comes along and wants to climb back in -- is Zombie #2 gonna let him, or will there be a zombie fight? Will the zombies share both the grave and the newly deceased Carole Wells? And what about now-dead John Carradine -- where's he gonna stay? After all, from the earlier scenes we know he's clearly at home in the grave... If this plot synopsis of the finale has left you confused, don't worry cause you're not alone.

Review: I'm writing this because I somehow felt being led to believe Dark Remains was a good movie. Whilst it's not the worst I've seen, it certainly isn't good.A Weak script, weak actors, and weak directing. Even if they can't afford big name cast, would it be too much to ask for a more attractive lead actress? It was painful to watch a plain actress through out the film with her dull performance. The story was a cliché and poorly scripted. The special effects were minimal. The "suspense" tricks employed repetitively here were hard to swallow.To be fair, Dark Remains is no worse than quite some of the Masters of Horrors' episodes. But not quite on par with quality movies yet. Dark Remains is only recommended for the hardcore horror fans who don't want to miss any movie in the genre, even if it's a poorly made one. As for anyone else, time should be spent on something more valuable - which should be extremely easy. Question: is it a negative review?

Review: The movie starts with a pair of campers, a man and a woman presumably together, hiking alone in the vast wilderness. Sure enough the man hears something and it pangs him so much he goes to investigate it. Our killer greets him with a stab to the stomach. He then chases the girl and slashes her throat. The camera during the opening scene is from the point of view as the killer.We next meet our four main characters, two couples, one in which is on the rocks. The men joke about how the woman would never be able to handle camping alone at a double date, sparking the token blonde's ambition to leave a week early. Unexpectedly, the men leave the same day and their car breaks down.. They end up arriving in the evening. When the men arrive, they are warned about people disappearing in the forest by a crazy Ralph doppleganger. They ignore the warning and venture into the blackening night and an eighties song plays in the background with lyrics about being murdered in the dark forest. The men get lost.In the next scene we realize that this isn't just another The Burning clone, but a ghost story! The women, scared and lonely are huddling together by the fire. Two children appear in the shadows and decide to play peeping Tom. Well they are obviously ghosts by the way their voices echo! Their mother appears with blood dripping from a hole in her forehead and asks the two ladies if they've seen her children, before disappearing of course. The children run home to papa and tell him about the two beautiful ladies by the river. This causes quite a stir and he gets up, grabbing his knife from atop the fireplace. "Daddy's going hunting," The little girl, exclaims with bad acting. It is apparent here, that the dad isn't a ghost like his children.Freaked out by something in the woods, the token blonde splits, running blindly into the night, carrying a knife. She encounters the father who explains he's starving and it will be quick. This doesn't make sense because of the panther growls we heard earlier (Maybe he's allergic! Are panthers honestly even in California?) She ends up wounding him slightly before getting stabbed in the head. A thunderstorm erupts and the men seek shelter, which turns out to be where papa resides. Clearly someone lives here because there's a fire and something weird is roasting over it. The children appear and warn them of papa, who shows up moments later. They disappear as soon as he arrives.For whatever reason, our killer only goes after females. He invites the men to have something to eat and tells us the story about his ex wife. We are given a flashback of his wife getting caught cheating. The old man doesn't tell them however that he kills her and her lover afterwards, but daydreams about it. We aren't given the reason for the children's demise. The men go to sleep and are left unharmed. The next morning the men discover the empty campground of their wives. After a brief discussion they split up. One is to stay at the campsite, while the other goes and gets help. The one that is going back to his car breaks his leg. We are then reunited with the children as they explain to the surviving woman that they are ghosts who killed themselves from being sad about their mother. They agree to help the woman reunite with her friendsThe following scene defies the logic of the movie when papa kills the guy waiting at the campsite. He was also dating or married to the blonde. Somehow the children realize he is murdered and tell the woman about it. She decides to see it for herself and obviously runs into the killer. Luckily the children make him stop by threatening to leave him forever. You know where this is going.Overall the movie deserves four stars out of ten, and that's being generous. For all its misgivings, the musical score is well done. It's still watchable too. There are some camera angles that look professional, and some of the sets are done well. The plot is unbelievable. There is such a thing as willing suspension of disbelief, but with the toad 6 miles away; I can't imagine the token blonde would take off like that in the middle of the night. I mean, come on!- Alan "Skip" Bannacheck Question: is it a negative review?
