I can't comment on all the films as i have only seen freddy got fingered, but for the price mentioned, surely this is not a bad deal.
alot of stupid humour, but at least more challenging than the scary movie enterprise. SMall spoiler here...not much though..lets face it, the storyline doesn't matter in this film! LOOK AWAY NOW, OR READ ON NOW!
if you find the idea of a man accusing his dad of fingering him, and going as far as breaking up his parents marriage just so he can avoid getting a job amusing, then this is for you!
