'Sucker Punch' Trailer

I don't really know what the hell this is about. Well, I do now because I read the description, but still.

Apparently set in the 1950's, the story is about some girl who is sent to a insane asylum and created this alternate reality where she plans to escape by stealing 5 objects. It sort of looks like 'Shutter Island meets Mortal Kombat'...or something.

It's a strange mash-up that could be good or bad. I don't know how to feel about it at this moment.
