From what I’ve read, they originally intended only on making 4 seasons, his high school years. Then they went and made, 5, which was ok, but could have ended there and been fine. Then six, which slid rapidly downhill. I couldn’t even finish the episode with Dean Cain (“Cure”) in season 7, and gave up on the show. Also, I’m not talking about individual episodes, there were some in each season that were fairly weak, but Kristen Kruek drew me back. My friend and I always made bets about how many times Chloe would run off crying in each ep. After they got out of the first few seasons and went away from the “meteor freaks” into the “Clark’s legacy” it got better. Then it got worse, far worse.
