Oh yeah, the other day I was looking at IMDB at the characters to see what else they were on, and I saw here it showed year ranges for when the actor was in Smallville, so I might have accidently spoiled a few surprises for myself.

Yeah, it's very tempting to want to see what happens in future seasons. I did some of that, and wished I hadn't....then again, the show really has never had any "shocks", most of what happens are things you can usually see coming.

To me, the strength of the show is in the character relationships, how some change for the better, some for the worse (Clark and Lex, Lex and Lionel, Clark and his father, etc.) I really did not expect to enjoy the show as much as I did. (though the most recent season that just ended, season 6, wasn't exactly one for the ages.
