Yeah, S2 and S3 both have curves of quality. They start off good (the early S3 episodes are FANTASTIC), then dip down into mediocrity and/or soap opera-tude mid-season, and then fight their way back up to being good again. Overall, I enjoyed S3 better than late S2 - there were some episodes that I just shrugged at, but there were some really, really good ones as well.
