Yes, I have watched it for several years. Last season, season 6, was a bit of a disappointment, but this season is better. Unfortunately, Michael Rosenbaum, who plays Lex Luthor, will not return next season. Also, the creators of the show Al Gough and Miles Millar will depart from the show after the conclusion of this season.
Well I wasn't really into it, but I have seen a lot of the episodes and I really like that show. It always keeps my interest, but I just stopped watching it one day for some reason.
