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: I really didn't like this movie because it didn't really bring across the messages and ideas L'Engle brought out in her novel. We had read the novel in our English class and i absolutely loved it, i'm afraid i can't say the same for the film. There were some serious differences between the novel and the adapted version and it just didn't do any credit to the imaginative genius that is Madeleine L'Engle! This is the reason i gave it such a poor rating. Don't see this movie if you are a big fan of L'Engle's texts because you will be sorely disappointed. However, if you are watching the movie for entertainment purposes (or educational as was my case) then it is an alright movie! Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: I am not a big fan of horror films, and have only seen a handful of them (and none of the "Halloween"s or "Friday the Thirteenth"s) - but I can appreciate a frightening horror film not because of gore. And I'm pretty sure this isn't scary. What's so spooky about a little plastic skull that pops up everywhere? In all of its appearances there are faraway establishing shots, so there's no real surprise in any of this film. (Not that a skull in of itself is that scary anyway, but . . .) The plot concerns Claus Von Bulow's third cousin (John Hudson), who marries a Donna-reed look-a-like (Peggey Webber, giving one of the worst performances ever) who begins seeing skulls and hearing the mysterious screams of a group of peacocks on her husband's mansion. Did I mention that her husband lost her first wife in a mysterious drowning incident? OOOOH!!!! Wonder who did it!!!! This is the same old plot about a rich boy trying to kill and/or drive their wife insane. If you want to see a well-done version of this stuff, try "Reversal of Fortune". And BTW, Jeremy Irons is one hundred times more talented than John Hudson. The MSTing was okay but nothing special; paired with the "Gumby" short, however, it makes for good viewing. Two stars for "The Screaming Skull"; eight stars for the MST3K version. And now, to paraphrase Mr. Von Bulow himself: "How bad is this film?" "You have no idea!" Question: is it a negative review?

SOLUTION:
yes
