I hate when Hollywood ruins amazing movies but making sequels... if there was ever a movie that should be left alone its Donnie Darko... its a fucking classic, and now some douche has come along and made a crappy sequel.

p.s. sorry if this is old news, i've heard about there being a sequel before, but didnt realize it was already released.
