Chuck (a geek would always want a girl who's out of his league maybe silently pine for them).
Reaper (it's ok, getting a bit dull and repetitive now)
Dexter (awesome, can't wait for the new series to start)
Simpsons (hasn't really in my opinion been good since series 17, 18 & 19 were terrible, and apart from one episode, 20's heading down the pan too)
Family Guy (Liked the earlier stuff, hated the middle stuff due to constant "It's like when XX did..." *scene out* stuff. Now it's not so bad it's better. Series 7 is really good actually.
Futurama (no need to comment, funny stuff)
American Dad (didn't think I'd like it, but there's just so much more breadth compared to Family Guy, very enjoyable)
