Review: As others have mentioned, this movie is similar to THE FLY (both versions) and the lesser known sci-fi flick ALTERED STATES. The big difference is that those two movies were well made by people who knew what they were doing and were good at it. METAMORPHOSIS did not have these advantages. METAMORPHOSIS is a potentially interesting science fantasy story that had the wrong people in charge of it and the wrong actors playing the roles.The story follows scientist Dr. Peter Houseman (Gene LeBrock), an obsessed man working on a genetic cure to aging and death. When the university he works for threatens to cut funding, he decides to inject the anti-aging serum into himself. As a result, Dr. Houseman spends the rest of the movie slowly turning into a lizard. And oh yes, watching the good doctor go through the process of becoming that lizard is a great joy. It really is so bad that it's good. Some of the lines are classic: "What WAS it?" "A nightmare...from the past!"Many of the reviews that I've read for this point up how stupid and ridiculous the last five minutes of this movie are. I'm just going to go ahead and spoil it: the good doctor goes from being a shuffling half-man, half-lizard thing to being what appears to be a man in a rejected Godzilla costume, when the police finally gun him down. In the final scene, some obnoxious kid is seen with a little pet lizard which he claims will never die, and the movie's heroine, Sally Donnelly (Catherine Baranov) evidently decides that the little lizard is the final incarnation of Dr. Houseman. The camera then gives us a close-up of the lizard's face; this is, I assume, the director's way of showing us that the lizard is EVIL. Yes, it is goofy, but I fell over laughing so I can't complain.I watched this movie because it was a part of the Chilling Classics 50 Movie Megapack that I purchased. I'm sure many of those who are reading this did exactly the same thing, as the 50 pack is the only way to see this movie on DVD. If you have recently bought the boxed set and haven't watched this movie yet, it really is worth your time, even if I did just ruin the ending for you. It might also be possible to find this movie online for free. Question: is it a negative review?

Review: This is only a response to the yahoo who says this movie is more realistic than the classic, genre defining MASTERPIECE, Jaws. Yes, brainiac, great whites(and other species of shark, bull, black-tip, oceanic white-tip, tiger)have been known to populate areas where easy prey is found. Humans don't often make it onto that menu, granted, but the shark in the film was repeatedly pointed out to be exhibiting abnormal behavior. It's not like it's never happened. The odds of a killer whale destroying nearly a whole town, singling out a human nemesis, sinking several dozen thick hulled North Atlantic fishing boats and knowing when certain people, all friends of the aforementioned "nemesis", are close enough to the water for it to reach, are so slim as to be laughable. Much like this turd of a Jaws knock-off. Laughable. Great white sharks are also known to frequently chew on boats, protective underwater cages and people on rafts and surfboards, as they look like seals from below. A shark the size of Bruce(if you don't know, look it up)would be more than capable of sinking a boat like The Orca(hey! that's the name of the blatant rip-off we're discussing!), as it would weigh upwards of 6,000 lbs. I could go on, but I don't need to. Jaws is amazing(better acting, better effects, better music, better writing), Orca is crap(BLATANT rip-off of Jaws, lousy writing, abominable effects, most ridiculous plot this side of an Olson Twins flick). It doesn't take a masters from Columbia University to see that. Watch better movies. Question: is it a negative review?

Review: this is a visual adaptation of manga with very little dialogue. what dialogue there is appears in word baloons as it would in the manga. the plot of this is existent but only vaguely accounted for. there is an issue of the manga on which this is based available in english in the blast books collection, 'comics underground japan', and it has actual captioned dialogue that explains the plot a bit more than here. i recommend checking that volume out if you liked this, as it explains some of the "plot" of the movie, which is otherwise inexplicable. animation wise this is pretty decent, good unintrusive use of computers and the images are for the most part realized well. it jumps in and out of episodes, as the characters, a cat and his brain-dead older sister cat wander in and out of a series of odd images: a boat, a circus, a desert. for a mere half hour they go through a number of semi-plots and settings, which leads me to believe that the director chose a number of issues of the long-running manga to adapt at random, but primarilly selected visually. knowing what's going on might somewhat increase appreciation. this reminds me mostly of the kind of stuff they used to play on the mtv show, cartoon sushi, in particular a short that features a cat chasing a man's severed butt-cheek around the house. only in this case the cats resemble hello kitty more and their adventure is expanded to include death and reincarnation and a number of other themes [though not all that easy to tell what's going on]. the dvd of this has director's commentary and a "making of" features, but i cant comment on those because i didnt get around to them. i'm giving this a 8/10 for now, here isnt much to compare it to in anime, and i hope for more like this.
