Clark's and Lex's return were too fast. Not even 6 minutes in, and they're back on the scene. Lana kills! She's evil!
Morgan and Helen are definate returns.
And didn't we hear the same Chloe/Lana and Clark/Lana convos last year? Move fuckin' on. Leave Clark single, keep the girl's interests indirect and add a green and ambitious Lois investigating the weirdness that occurs at Smallville.
And if they're gonna introduce Wayne, have him as Lex's rival. He should be just as cunning and more mature than Luthor, and possibly even one-up him. Wayne and Kent shouldn't solve a mystery together or none of that shit. Wayne and Lex play mental chess, and the pieces are their shares of their companies. Maybe Wayne small talks with Kent as he leaves the boonies... I mean, Smallville. That's it.
For some reason, I always wanted to see Kyle Rayner on the show.
