Fringe! It's in it's last season but it's so good if you like sci-fi. But it'd be best if you watched it from the beginning, otherwise you probably won't understand it.
To be honest, I have been really into breaking bad. I have literally been spending more time watching it then studying which is not a good thing. Its crazy how Walt went from the father, Hal on Malcom in the middle to this sort of a role. Well done by him.
