I agree with smy: I prefer to watch a series, even if it's seasonal, one episode after the other.

If I have the money I'll probably always have TV service for things like specials, Fox News and CNN. However for really good shows I like waiting for the whole season to be over, like: Mad Men, Burn Notice, Breaking Bad, Californication, Dexter, Eureka, Stargate Universe, Sons of Anarchy, True Blood (S02 was weird, haven't seen S03 yet), Weeds, Modern Family, The Walking Dead, Top Shot and V. I am doing this more and more though. Like to watch 2-4 episodes at a time if possible. For new shows in the last year I've watched the 1st episode and going to wait until it's over to see the whole season, like Nikita...
