+"A rating of ""1"" does not begin to express how dull, depressing and relentlessly bad this movie is."
+Hated it with all my being. Worst movie ever. Mentally- scarred. Help me. It was that bad.TRUST ME!!!
+"Long, boring, blasphemous. Never have I been so glad to see ending credits roll."
+This film made John Glover a star. Alan Raimy is one of the most compelling character that I have ever seen on film. And I mean that sport.
+"Were I not with friends, and so cheap, I would have walked out. It failed miserably as satire and didn't even have the redemption of camp."
+For pure gothic vampire cheese nothing can compare to the Subspecies films. I highly recommend each and every one of them.
+"A great film in its genre, the direction, acting, most especially the casting of the film makes it even more powerful. A must see."
+"This is a terrible movie, don't waste your money on it. Don't even watch it for free. That's all I have to say."
+I wouldn't rent this one even on dollar rental night.
+"More suspenseful, more subtle, much, much more disturbing...."
+This is a good film. This is very funny. Yet after this film there were no good Ernest films!
+A touching movie. It is full of emotions and wonderful acting. I could have sat through it a second time.
+"Great movie - especially the music - Etta James - ""At Last"". This speaks volumes when you have finally found that special someone."
+If you've ever had a mad week-end out with your mates then you'll appreciate this film. Excellent fun and a laugh a minute.
+"I think it's one of the greatest movies which are ever made, and I've seen many... The book is better, but it's still a very good movie!"
+Brilliant and moving performances by Tom Courtenay and Peter Finch.
+The characters are unlikeable and the script is awful. It's a waste of the talents of Deneuve and Auteuil.
+You've got to be kidding. This movie sucked for the sci-fi fans. I would only recommend watching this only if you think Armageddon was good.
+Ten minutes of people spewing gallons of pink vomit. Recurring scenes of enormous piles of dog excrement - need one say more???
+"As usual, Sean Connery does a great job. Lawrence Fishburn is good, but I have a hard time not seeing him as Ike Turner."
+This movie is terrible but it has some good effects.
+You'd better choose Paul Verhoeven's even if you have watched it.
+"Brilliant. Ranks along with Citizen Kane, The Matrix and Godfathers. Must see, at least for basset in her early days. Watch it."
+"I don't know why I like this movie so well, but I never get tired of watching it."
+The one-liners fly so fast in this movie that you can watch it over and over and still catch new ones. By far one of the best of this genre.
+"Don't waste your time and money on it. It's not quite as bad as ""Adrenalin"", by the same director but that's not saying much."
+"Read the book, forget the movie!"
+This is a great movie. Too bad it is not available on home video.
+"Very intelligent language usage of Ali, which you musn't miss! In one word: (eeh sentence...) Wicked, so keep it real and pass it on!"
+Primary plot!Primary direction!Poor interpretation.
+"If you like Pauly Shore, you'll love Son in Law. If you hate Pauly Shore, then, well...I liked it!"
+Just love the interplay between two great characters of stage & screen - Veidt & Barrymore
+"This movie will always be a Broadway and Movie classic, as long as there are still people who sing, dance, and act."
+This is the greatest movie ever. If you have written it off with out ever seeing it. You must give it a second try.
+"What a script, what a story, what a mess!"
+"I caught this film late at night on HBO. Talk about wooden acting, unbelievable plot, et al. Very little going in its favor. Skip it."
+This is without a doubt the worst movie I have ever seen. It is not funny. It is not interesting and should not have been made.
+Ming The Merciless does a little Bardwork and a movie most foul!
+This is quite possibly the worst sequel ever made. The script is unfunny and the acting stinks. The exact opposite of the original.
+"This is the definitive movie version of Hamlet. Branagh cuts nothing, but there are no wasted moments."
+My favorite movie. What a great story this really was. I'd just like to be able to buy a copy of it but this does not seem possible.
+"Comment this movie is impossible. Is terrible, very improbable, bad interpretation e direction. Not look!!!!!"
+"Brilliant movie. The drawings were just amazing. Too bad it ended before it begun. I´ve waited 21 years for a sequel, but nooooo!!!"
+a mesmerizing film that certainly keeps your attention... Ben Daniels is fascinating (and courageous) to watch.
+"This is a very cool movie. The ending of the movie is a bit more defined than the play's ending, but either way it is still a good movie."
+"Without a doubt, one of Tobe Hoppor's best! Epic storytellng, great special effects, and The Spacegirl (vamp me baby!)."
+I hope this group of film-makers never re-unites.
+Unwatchable. You can't even make it past the first three minutes. And this is coming from a huge Adam Sandler fan!!1
+"One of the funniest movies made in recent years. Good characterization, plot and exceptional chemistry make this one a classic"
+"Add this little gem to your list of holiday regulars. It is sweet, funny, and endearing"
+"no comment - stupid movie, acting average or worse... screenplay - no sense at all... SKIP IT!"
+"If you haven't seen this, it's terrible. It is pure trash. I saw this about 17 years ago, and I'm still screwed up from it."
+Absolutely fantastic! Whatever I say wouldn't do this underrated movie the justice it deserves. Watch it now! FANTASTIC!
+"As a big fan of Tiny Toon Adventures, I loved this movie!!! It was so funny!!! It really captured how cartoons spent their summers."
+Widow hires a psychopath as a handyman. Sloppy film noir thriller which doesn't make much of its tension promising set-up. (3/10)
+The Fiendish Plot of Dr. Fu Manchu (1980). This is hands down the worst film I've ever seen. What a sad way for a great comedian to go out.
+"Obviously written for the stage. Lightweight but worthwhile. How can you go wrong with Ralph Richardson, Olivier and Merle Oberon."
+This movie turned out to be better than I had expected it to be. Some parts were pretty funny. It was nice to have a movie with a new plot.
+This movie is terrible. It's about some no brain surfin dude that inherits some company. Does Carrot Top have no shame?
+Adrian Pasdar is excellent is this film. He makes a fascinating woman.
+"An unfunny, unworthy picture which is an undeserving end to Peter Sellers' career. It is a pity this movie was ever made."
+"The plot was really weak and confused. This is a true Oprah flick. (In Oprah's world, all men are evil and all women are victims.)"
