For some, the Smallville finale left viewers with - well, a serious case of red and blue balls. We've been waiting ten years to see Tom Welling in costume -- and instead, were left with a far-away computer generated approximation.

The argument has been made that this was never the story about Superman, but that still didn't stop people from picking the lack of seeing Tom Welling in a non computer generated, full frontal Superman suit as the biggest "What The Heck?!?" moment of Season 10. 33% - or 1 in every 3 votes - made that their top pick.

The fact that there's a Smallville comic book in the TV universe - which you'd think would give away Clark's secret to the world - came in second place with 387 votes. Third place for "What The Heck?" goes to the erasing of Lex's memories in the series finale - which, unless he gets them back (which I assume he would), means his entire Smallville journey was pointless. Oops! That one had 256 votes.
