Ben 10 Alien Force - Not as bad as I remember it, and it actually had some good parts. Kevin, despite being nothing like the first series incarnation, was easily the best character on the show, while many of the aliens (Big Chill, Lodestar, and especially Rath, who, if you never watched the show, is basically the fusion of Hulk Hogan and Wolverine wearing a Tony the Tiger outfit) were great. However, the Highbreed plot was bad, Vilgax was worst, and I hated Swampfire and Jetray.
Yu-Gi-Oh! Season 4 - Meh, it was better than the Noah saga, but still pretty bad.
Whose Line is it Anyway? - Still far and away the best show on television.
