Review: A great suspense movie with terrific slow camera-work adding to the dramatics makes this a treat to watch and enjoy. Director-writer Brian de Palma does a super Hitchcock-imitation (many called it a "ripoff") with this film and the 2.35:1 widescreen DVD is a must to fully appreciate the camera-work (and several scenes with people hiding on each side which are lost on formatted-for-TV tapes).The downside of the movie, at least to anyone that has some kind of moral standard, is the general sleaziness of all the characters, including the policeman played by a pre-NYPD Dennis Franz (who has hair here!). The opening scene is still shocking with a fairly long shower scene of Angie Dickinson that is quite explicit, even 25 years after its release. The film has several erotic scenes in it as Dickinson (if that is really her on the closeups) and Nancy Allen are not shy about showing their bodies.There is not much dialog in the first 20 minutes and no bad language until Franz enters the picture after the murder. The first 36 minutes are riveting and even though it's apparent who the killer is, it's still very good suspense and fun to watch all the way through, particularly for males ogling the naked women.

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: I had just reached thirteen when I first saw this series and I am watching it again, on DVD, over thirty years later. The pictures over the opening credits have never left me. It has affected my view of the world and the peoples in it. My parents were with me long enough to have seen the series with me, and we always discussed the programme afterwards. It gave me a love for studying history and the highest marks I got in our school's public exams!Sir Laurence Olivier's voice and delivery is timeless and perfect. I get the feeling that the people who lived through it would feel that this is their version of the history of the Second World War. I cannot imagine ever getting bored looking at it. Maybe an similar Cold War series could now be contemplated, although who could replace Sir Laurence is difficult to imagine.Buy it! Question: is it a positive review?
