Oh yeah. Xerxes was so amazingly bad. I'm kind of unsure how someone dressed like they just stepped out of a drag club is supposed to be menacing and scary. Then again, he probably wasn't supposed to be scary - he's probably just there to show how awesome and manly the Spartans are.

I also think the british accents were a vain attempt to make the dialogue sound smarter and less idiotic than it really was. That and the epic amount of shouting. Not that it worked... lol.
