Bad Cast, Why I loved 1 + 2, but hated 3.
In short, ugly cast, and unlikable characters.
The leading female character is a made to look like a plain Jane. But also a plays a b***h. The leading male character is kinda like a snot nosed, weak minded loser. They don't necessarily have to be good looking, but I would like to follow someone that has some control of the situation. Give me one or the other. Why would I want to spend 90 minutes following these unlikable characters when they probably can't even save them selves as they are being stepped on by the people they are trying to save?
The little bit of saving grace is that at least the gore level is up to par with the other movies.
