Personally, I don't understand why "Smallville" is still on. Shouldn't Clark Kent be in Metropolis by now? Besides, you can only do so much in a small-town setting. The more third-tier comic book characters they add to the mix, the more "Smallville" is augmenting their borrowed time and therefore losing touch with the original premise of the series.
As for J.Lo, I'm no fan but her musical career still has legs. I think she released a new disc about two months ago.
