The role reversal
I really enjoy this movie but one thing that bothers me more and more every time I watch it is that the revenge/turning of the tables at the end is not 100% justified in my opinion. Yes, Stuntman Mike chased them and nearly killed Zoe, literally leaving her for dead. Kim had every right to shoot him in that moment. But, as much as I enjoy what happens next, it doesn't really make sense for them to hunt him down, chase him and kill him while putting other people's lives in danger. They all got away without a scratch!
I think it would have been slightly better if they didn't leave Lee behind and instead used cell phones as collateral (which would explain why they wouldn't call the police). And then somehow during the first chase, Lee could be killed. This would force them to get revenge, it would still be over the top but slightly more justified and all the girls would have looked much more sympathetic. I didn't like that they left Lee behind with a potential rapist to begin with.
