The Big Bang Theory finale was completely predictable, but it was exactly as it should have been. Seinfeld...I guess you could say the same; I was hoping for more. It's still my favorite all-time series. M*A*S*H's finale was good, but...It dragged out too long, and I didn't like the Winchester angle. I'm going with Breaking Bad. It had everything we needed to see, plus a good twist near the end.
