Yeah, I followed it into a couple of episodes of the fourth season, and decided I just wait for the series to wrap up and pick up the last of the dvds.
I will say this, I have mad respect for the producers of the show when they made the announcement that after 5, they were done, they were finishing the story they set out to tell. If only Smallville had decided to do that, I wouldn't have to keep sending death threats to Tom Welling.
