Oh, Tom Welling can act. Haven't you seen the show? Sometimes he gets sad, and then other times he gets very angry! I saw an episode where they show him some red kryptonite (which episode was it, rex?), and he got all mean and nasty with his friends. You could tell he was evil because he would arch his eyebrows and do a wicked smile (also he has a black leather jacket for these occasions). Welling has loads of different faces and different tones of voice that he uses to let you know how he's feeling (the Top Forty songs help, too). Smallville is a roller coaster of emotions, with Tom Welling on the front seat.
Maybe Brandon Routh doesn't act, but you can't say the same about Tommy Welling. He acts like every other underwear model turned soap opera actor. Therefore, Welling and Routh are in completely different categories.
