Review: ****Don't read this review if you want the shocking conclusion of "The Crater Lake Monster" to be a total surprise****A claymation plesiosaur rises from the depths of Crater Lake to wreak havoc on a group of local rednecks, not to mention your fast forward button. To call "The Crater Lake Monster" amateurish is to overstate the obvious. If you aren't a fan of low budget drive-in films, you probably wouldn't be looking here in the first place.The problem with the movie is that when there's no monster action going on, it really sucks and goes nowhere. The script is very Ed Wood-ish, in that it's utterly contrived in the way it sets up the main action sequences. Nothing is too outlandish for "The Crater Lake Monster". It explains its dinosaur by having a meteor crash into Crater Lake, 'superheating' the water to the point where it incubates a dinosaur egg that has apparently been resting at the bottom of the lake for millennia. Even if we could accept that the egg could have been lying there for so long and remained uncovered and viable, wouldn't "superheating" the water to such a high temperature cause most of the lake to evaporate? Other than some token fog in one or two scenes, we see no evidence of the water being hot, other than a few lines in the script.The script is padded rather obviously in a few sequences, and it will do anything to get the characters near the lake so that they can be menaced by the claymation dino. A couple just passing through experiences car trouble and while their automobile is being serviced, they decide to rent a boat and head out into Crater Lake. Hmmmm...do you think these strangers in the story could be there so they would run into our title monstrosity? In a sequence that's just plain bizarre, a drunk robs a liquor store and decides to murder the cashier and a bystander instead of paying four dollars for a bottle of booze. A car chase ensues, and wouldn't ya know it...they end up right by the lake. Snack time for Cratey! Yeah, it's not hard to figure out, and you're so far ahead of the script that you're irritated when it takes another ten minutes for these scenes to unfold.The shamelessness of it all is endearing, and I really want to like "The Crater Lake Monster". I just can't do it. There's not enough here to go on, and this is more of a movie to put on during a party, because you could talk right over it and it wouldn't matter. The film has a slim list of the things going for it, the most important being the dinosaur itself, which appears in three forms: a shadow puppet, a large model head that is dragged woodenly through the water, and a fully realized claymation insert that actually looks pretty good. There are also a pair of lovable hicks in it, and they carry the majority of the intentional humor in the movie. A downbeat ending leaves us mourning the death of both the monster AND one of our beloved hicks, so every good thing about this film is dead by the end of it. Why was I so affected by this conclusion? Was it the mournful song played over the closing credits? Or was I just weeping inwardly for the time that I waste watching films like this?

Review: The two things are are good about this film are it's two unknown celebrities.First, Daphne Zuniga, in her first appearance in a film, young and supple, with looks that still encompass her body today, steals the very beginning, which is all she is in, and that is that. She is obviously just starting out because her acting improved with her next projects.Second, the score by then known composer Christopher(Chris) Young is what keeps this stinker from getting a one star...yeah, I know one star more is not much, but in this movie's case, it is a lot.The rest is just stupid senseless horror of a couple a college students who try to clean out a dorm that is due for being torn down, getting offed one by one by an unsuspecting killer, blah, blah, blah...we all know where this is going.Watch the first eighteen minutes with Daphne Zuniga, then turn it off.

Review: Some gorehound-friends recommended "Live Feed" to me, and basically I can't really complain as the film certainly does deliver copious amounts of gross smut and buckets full of sleaze, but it is of course not a very good film. More than obviously cashing in on the latest trend in horror cinema, the so-called Torture Porn, Ryan Nicholson tries to surpass every other film in this sub genre (and that includes the role models "Hostel" and "Saw") with its sick & twisted make-up effects and thoroughly depraved shots of naked co-eds tried up, suffering and begging for their lives. There's no actual plot to describe. Five utterly brainless twenty-something friends take a trip to Asia. One of them has Asian roots, but other than that I don't really know why they opted to travel there instead of to Cancun. They're clearly not interested in the continents culture and even cause a hectic scene when they witness a local butchering a cute puppy dog on the market. The quintet subsequently dives into the lurid night life and one of them accidentally insults the leader of a criminal clan. A simply apology clearly doesn't suffice, as the gangster follow them into an adult theater and gradually subject all of them to vicious torture. One girl has her breast impaled and another poor wench even has a poisonous snake shoved down her throat; yikes. "Live Feed" is surprisingly boring despite of all the bloodshed and the amateurish production values are quite difficult to overlook, even if you're used to watching independent fan-boy trash cinema like this. The fat bloke depicted on the cover, an oriental S&M executioner, is admittedly quite cool and he's also the most talented of the whole bunch, because he at least keeps his mouth shut the entire time. I wouldn't exactly recommend this pile of filth, but hey, if you like loud & hideous metal music, nauseating torture footage and dim-witted losers, go right ahead and watch!
