Query: Derivative, and lacks any internal logic

One of the worst movies I've seen in a while. Starts off kinda sorta promising, and then turns into a sub-par survival horror movie that is derivative of every other such movie you've seen. It has no internal logic, and frequently breaks the rules it has established earlier. Nor does it earn its ending. I can't say more without giving a lot away. Re-watch some Walking Dead 'sodes instead. (Or watch the 2006 horror movie of the same title, which is a genuinely good movie.)
