While the latest Harry Potter film, Harry Potter and the Half-Blood Prince is the first installment in a while to be rated PG, that doesn't mean it's any less messed-up. Sure, there's less blood (even though it's the first to put the word "blood" right in the title), but Harry still receives a nasty beating, there are teen make-out parties galore and at least one person gets murdered. Oh, and there are also zombies. Fricking zombies! In celebration of the scariest PG film we've seen in a while, we thought we'd run down the most effed-up moments in the franchise's first five films. No spoilers for Half-Blood, unless you count us mentioning zombies earlier. Too late!
