Truth be told, it's not so much the series I dislike as it is some of the fans. Seriously, I've encountered several groups of fans online that are overbearingly obsessed with the series and insist that it is the greatest thing since sliced bread. One note of criticism and they attack you like a pack of ravenous wolves. Heck, I might actually be more inclined to actually read the friggin' books if it weren't for some of the fans.
And seriously, whoever the heck got the idea of dipping Cedric Diggory in a vat of glitter and calling him a vampire musta been smoking some good stuff. Really, I've had enough of his effeminate self in Harry Potter that I don't need to see him on a movie trailer every time I turn on the TV.
I like this forum because at least the first post points out some serious flaws in the series other than "it's stupid".
