The shows that I'm currently watching:

Heroes (season 4 - airing)The Mentalist (season 2 - airing)Supernatural (season 5 - airing)South Park (season 7)Mutant X (season 2)

Heroes has returned to some of its former glory. (They could show more of Peter, though...)

The Mentalist is still made of absolute win.

Supernatural has had a lot of fun this season, but I'm not sure of the overall Apocalypse storyline... and from time to time it seems the writers of the show are trying to avoid the topic too.
