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: I don't know why some people criticise that show so much.It is a great, funny show - probably not the right material for mainstream prime-time, but still...The family dynamics are funny, and all in all the same you see in most comedy shows. The supporting characters are absolutely hilarious. The plots of the individual episodes and the frequent Siegfried & Roy jibes are only just above average, but ever so often you have sub-plots or one-liners that make you roll on the floor laughing.This show was well worth the 8 Pounds I paid for it.rating: 8/10 Question: is it a negative review?

no

Review: This movie displays the kind of ensemble work one wishes for in every film. Barbara Bain and Donald Sutherland (who play husband and wife)are positive chilling, discussing the "family business" as if it were a grocery store or a dry cleaners. Macy, Campbell, Ullman, and Ritter are also terrific. They play off each other like members of a top-notch theatrical troupe, who realize that a quality product requires each actor to support the others unselfishly. And finally, there's Sammy (David Dorfman). What an amazing performance from a child...and what an uncanny resemblance he has to Ullman, whose son he plays!We're treated to a unique story in "Panic," and that's a rarity in these days of tired formulaic crap. The dialogue is sharp and smart, and this relatively short film nevertheless has the power to elicit a full range of emotions from the viewer. There are places to laugh, to be shocked, to be horrified, to be saddened, to be aroused, to be angry, and to love. It's not a movie that leaves you jumping for joy, but when it's over you're more than satisfied knowing you've spent the last ninety minutes experiencing a darn good piece of work.More of us would go to theatres if we were treated to quality fare like this. When are the powers that be in Hollywood going to wake up? It's a real shame when something this good fails to get exposure beyond festivals and households fortunate enough to have cable.
