Small spoilers ahead, so beware.

The best bit so far are the last two minutes of episode 13 of season 3.

Walter calls Jesse. Mike has a gun pulled on Walt.

You have a 20 minute head start. Go do it.

Everything about it, the script, the acting, camera work, editing, music, the whole gestalt is delightful, and of course it has a bitter-sad ending.

One more thing. Skyler knew, from the middle of Season 3, that she is a criminal. So all the analysis of her meetup with Hank in the last episode that theorized somehow that it hadn't dawned on her that she goes to jail too, is nonsense. And she doesn't have terminal cancer as far as we know.
