I have read other reviews of this movie, and a lot of people are comparing Tamara with 80's Horror Films. I can see the comparisons, the way the movie follows a formula, and although it isn't a blatant rip-off of one certain movie, it most certainly shadows certain scenes and characters throughout.
Tamara is a quiet introvert with a talent for writing she is in love with her teacher even though he is older and married and obviously off limits. She wears outdated clothing, her eyebrows are in need of waxing, her hair is mousy and unruly, she hunches over, it's a perfect caricature of the "nerdy ugly beautiful girl" waiting for her big break. What is different about her is that we know she is a witch, that she has performed spells on the poor teachers wife so she wont have kids, Yes she is bullied in the shower room a la Carrie style (without the tampons) but I for one didn't feel sorry for her. She wasn't innocent, the bullies thought they would be teaching her a lesson about her feelings for teach and for exposing them for taking steroids, although that was the wrong thing to do, I do believe that Tamara needed to be shown how ridiculous the fantasy of this man leaving his wife really was. Her death was an accident, and they should have gone to the police, although Tamara would have turned into the Vamp regardless, so I understand that plot direction. Why involve the cops, when we are supposed to see how the guilty get what's coming to them through her vengeance.
What ensues is her taking them out one by one, using them as her weapons against each other, and against her ultimate enemy, the teacher's wife. The Special Effects were both chilling and disappointing. I loved the "hear no evil, speak no evil, and see no evil" kill, but some of the others were muddled by poor CGI and prosthetics, in that aspect it really copied the 80's motif. In the end, we don't like her and we want the survivors to live, as it should be, and the sacrifice of an innocent for the good of the group is beyond copying the 80's it is true for stories of human nature from all times. I am sure that every male watching thought her demise was a waste, but its also true that her beauty was completely false, enhanced by witchcraft and her hatred, skin deep, and just as fragile.
