Warner Bros TV has been lobbying hard to get Michael Rosenbaum into the Smallville finale and it looks like they've succeeded.

"I'm simply doing it for all of the fans out there who made Smallville the great success it is," Rosenbaum said in an official statement. "I appreciate all of their passion, their relentlessness and even their threats. Ha ha. I can't wait to hug the old crew back in Vancouver one last time and see all of my old friends once again..... Oh, and for Lex to become the badass he's destined to be."

Rosenbaum was the best thing on Smallville until he exited in season seven, so with his promised reprise and suggestions that Tom Welling may finally pull on the cape, could Smallville be worth watching again?
