5/10
This one starts off the day after the first movie ends. Basically the wife dies in the first one and some dude bleeds on a bed and she gets reanimated. I guess the doctor is like totally interested in the evil dudes and wants to like see them. So the doctor gets some loonies and the chick heals and gets her skin back. But it's nasty like looking at her as she had no skin and she was like all kissing on him.
So the doctor gives the cube to this loony chick who likes to solve puzzles and she calls them and like the daughter, the puzzle chick and the wife and doctor all go into the evil dudes world. Anyway it ends up where the wife kills the doctor and the doctor comes back as a evil dude. The wife ends up with her skin ripped off. And the puzzle chick and daughter leave their world.
Well the regular world is now different and is like transforming so they have to go back to the other world to solve the cube. Well they get trapped in a room with the evil dudes and like try and get them to remember than they are human and they do and the doctor comes in and basiclly kills the other evil dudes (so basically pinhead is a pussy). Then blah blah blah the puzzle chick solves the puzzle and their world like collapses or something and they gotta run out into their world before the door closes. Then like at the end they show the cube but it's like covered in faces and stuff. It was weird.
