Cabin in The Woods WORST MOVIE EVER

Justin Bieber: The Movie.

Plus, it was shot in 3D.. How could it get any worse?

I agree with everyone.

In my opinion, Quantum of Solace.

Mostly all Japanese or Mexican movies lol (not trying to be mean and stuff)

Jack Frost. Snowman that kills people. Need I say more?

every fcuking twilight movie ever made

"FM" ... 1978... starring Martin Mull... music by Steely Dan ... if you never see this movie, consider yourself very lucky....
