I get it, that some character decisions can break a movie for people. I've had the same thing happen to me, even with movies that are considered classics (and this will not be in that category). But if you are willing to jump that flaw/hurdle and see past it, you will have "fun" with this.
It's actually a tight little movie with twists upon twists and a level of "how far would you go" and "what would you do" sort of scenario. Of course if you say you're rational, than you might have avoided a couple of things, but it's not always depending on one person what the outcome is going to be like. So sit tight and enjoy this thrill ride - if you can
