I just finished Stargate Atlantis; what a massive pile of terrible that finale was, somehow beating out Vegas for the worst episode. SG1 didn't fair much better when it came to a finale, and Universe, well, the less said about that abortion, the better.

Of course, the series had been on a decline starting with season 4, so I guess it wasn't a surprise they would have screwed it up, but the sheer amount of stupid in the episode...
