PROBLEM: Review: not your typical vamp story, not bram stoker or anne rice here. a truly original vampyre story. these vampyres are genetic mutants who the sunlight don't bother. they are pure evil to. the film is not perfect. many of the actors are clearly amateurs. the two leads who play van helsing and rally the vampyre chick are pretty good though. the film is intensely violent which may disturb some people. also it is loaded with scientific detail that many will find hard to understand and may get bored with. i was sold on the clever storyline and the couple good performances. no telling how successful this film could be if they had a bigger budget and it got mass distribution Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: I figured that any horror film with Orson Welles in it would be weird. Necromancy sure was but it was a little too weird for it's own good. The film does indeed have a creepy feel as it deals with a coven of satanists/witches in a small town and a young woman's attempt to escape them. The director though seems to be deliberately trying to confuse the audience by using flashbacks and dream sequences. By the finale, there are too many unanswered questions. What's worse, as the story is so confusing, it's pretty hard to root for any of the characters. It seems odd that Welles would agree to headline this film especially since he doesn't have that much to do. Maybe someday they will put out a tape of the outtakes and bloopers from this movie. Now that would really be fun! Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: An inventive, suspenseful exercise in claustrophobia. A Japanese thriller that sets itself a tough challenge by being entirely set in two rooms. Not completely successful, but taut, surprising and well-acted. One might find the film somewhat reminiscent of SAW  two men trapped in room and pitting against each other  but unlike that film it dares to stay with its premise and keep the hero locked in his cell throughout the film. It's like watching a lab experiment. Some might find the contained suspense tedious, but this reviewer found it enthralling. The sound and imagery of the film are stunningly well realized. This is a certainly a good film to use to show off a good home video system. Just right for a late night movie fest, when one is in the paranoid mood. It certainly kept me awake that night. Question: is it a positive review?

SOLUTION:
yes
