Has anyone seen Identity (movie)?

I JUST saw it. It’s like one of those mind benders that chop off your ears if you think too much.

Did anyone get it? I have no idea what was going on until afterwards I read an explanation, which still didn’t explain much.

Who’s the bald guy? did the murders 4 years ago have anything to do with the rest of the movie at all? Those 10 main characters at the motel were simply created out of nowhere? They didn’t represent anything? What’s with the kid and his muteness?
