I think this movie tries to be a bit more than your typical revenge flick but it kinda comes up short. They really needed to make at least a little bit of an effort to make the revenge scenes more realistic. One of the biggest issues is the sheer size of the main character. If you are going to cast someone this small you need to do a better job of creating realistic scenarios where she kills these clearly stronger guys. Also her ability to avoid suspicion is ungodly.
Detective: You were the only person at the dead guy's house the same night he died?
Girl: Yes.
Detective: Why'd you come over?
Girl: To talk. He wanted to have sex, I didn't feel like it soz I left after a few min. he must've died after I left, that's so weird.
Detective: Alright seems good to me I don't need any more follow on questions, I think I'll go grow a beard now.
