I also like Legend of the Seeker and Fringe! But I STILL wouldn't want to miss out on Smallville. Sorry peeps, I'm just one of those die-hard fans that see the deficiencies in the show but still love it.
I like that people see flaws in the show; those critics will keep the writers on their toes, but I don't think that the episodes are all that bad. Yes, I'm frustrated with the twist and turns of CLOIS, but I do understand that they can't really conclude yet on Lois and Clark because everything from season 1-9 is still a prelude to Superman. If they do, then what's going to be left for future seasons?
They also need the fillers for the show; that's the only way they can develop sub-plots and lengthen the season. They also need the cliffhangers in the end to make the viewers want to see the next episode (it's working for me! although i can understand how some fans would be too frustrated, enough to make them totally give up on watching the show). But aren't those the strategies of all shows?
