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?
yes

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?
yes

Review: It's about time we see a movie that stays unbiased towards these old Indian traditions. At times it is clear how most of the 'doctors' are charlatans, even lying about how they don't charge their clients. While they are wearing their gold watches, the 'donation' box is mandatory. Notice that there are only a couple of people who get 'cured' while we see quite a few cases.Keep in mind while watching that ingesting mercury is not toxic and that the smallest Indian bank note is 5 rupee, while the average salary in India is 1,700 ru/month. Question: is it a positive review?

no
