PROBLEM: Review: The first 45 minutes of Dragon Fighter are entirely acceptable and surprisingly watchable. The characters are believable and interesting. The cloning lab looks really high-tech. After that, it all collapses. The characters start behaving idiotically, and a new subplot is introduced from nowhere about a fusion reactor (and this is supposedly "present day") going critical, the only plot justification of which is that it is required to kill the dragon - only it doesn't. The finish is incredibly weak. One wonders what made a movie that started out so well turn so wrong.All the characters except Dean Cain are played by Russians. This results in some weird situations and details, like the character being played by Vessela Dimitrova being called "Bailey Kent" despite her heavy accent (and despite her, on one occasion, inexplicably switching to *Spanish*!).Because of the decent start, I considered rating this movie a 5, but it really was more disappointing than that, so I only give it 4. Question: is it a positive review?

SOLUTION: no

PROBLEM: Review: Last of the Johnny Weissmuller Tarzan films and a good thing too, as this is easily the worst of the 12 films he made over a period of 16 years. No mermaids are featured here either as a beautiful island woman tries to escape the clutches of her people, who worship a god and try to force her to be its bride. She finds Tarzan and Jane, who try to protect her. George Zucco is present as a potentially villainous High Priest but isn't used to his full advantage. Also on hand and worthy of mention is a hugely annoying guitar player/singer who goes into song every so often. Even the "great" Robert Florey can't aid this one.*1/2 (of four) Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: This movie is the worst movie i have ever seen... it is humorous how bad it is.. the entire time i was watching it i half expected music to start and the doctor starts dancing..(i've seen porno's with a better plot) When the raptor was trying to get in the door i think someone was throwing a plastic doll against the door from about 2 feet away. But as i said it is so bad you need to watch it so that you can see just how bad it is me explaining it isn't going to do anything compared to if you watch it .. i don't recommend renting it but if it comes on TV watch it for about 30min just to see what i mean. I couldn't watch more than 30min but if you can sit through the whole thing then you have some good willpower Question: is it a positive review?

SOLUTION:
no
