The last season if Smallville is actually really good. The 200th? Episode where he goes to the future and meets himself is one of my favorite Superman stories. It's pretty great.
And wasn't it Welling who refused to wear the suit at all. I think they probably would have thrown him in it by season 8 or 9 otherwise.
And the Smallville season 11 comics are actually really good. I like the versions of Batman and Wonder Woman they introduce.
