Breaking Bad. If you haven't seen it, it HAS to be your next tv show to watch.
^^ I just started watching it, missed the first season--it is good.
If you haven't watched either of these and you are a Sci-Fi/Fantasy fan, they are musts:
Walking Dead (better zombie scenes than most Hollywood movies!)
Game of Thrones (dragons are always cool....seeing the main blonde chick get naked makes the whole thing worth while!)
