Ooof, okay, "Tamara" (2005) is basically the perfect example as a contrast to the thin line that I think "I Spit On Your Grave" stays on the "done well" side of for #FemRevengeFlicks .
Before I dive into what goes wrong here, for me, I'm going to do a quick plot description.
Tamara is a nerdy girl in high school who gets bullied by some popular kids and has a crush on one of her teachers. The bullies decide to punish her by convincing her that the teacher wants to be with her and lure her to a hotel room, where they record video of her getting undressed before revealing the "prank." A fight ensues and she dies accidentally during the struggle. Rather than go to the authorities, the bullies decide to bury her body in the woods and cover it up.
Well, little did they know, she practiced real witchcraft and the "love" spell she cast to bind her and her teacher worked. She comes back to life and shows up at school on Monday, much to their shock. What follows basically plays like a slasher movie, with her taking off the bullies one by one in revenge.
It finally ends when the teacher finds out that the spell will keep her alive as long as he is alive and they are not together. To protect his wife, he tricks Tamara and jumps off a building with her, killing them both and ending the spell.
TLDR: Basically, "The Craft" + "I Know What you Did Last Summer" + "Fatal Attraction" = "Tamara"
