My wife and I insist that Breaking Bad is one of the best dramatic television shows ever.
Seriously: EVER.
It will blow your mind every week/episode. It's classic one-step-forward-and-two-steps-back character development. Every climax is just a setup for the next escalating ordeal.
You cannot conceive where Breaking gets to in Season 5. You would not be able to guess with 1,000 guesses --not a chance.
I've never tried meth, but I assume it's as addictive as this show.
