(S03E04) Even on cable shows that are tightly plotted because of their short seasons, there are sometimes episodes that feel more like they're setting things up for the episodes to come rather than pushing the story arc forward. This week felt like one of those episodes.

I wouldn't classify it as a "throat-clearing" kind of episode, because, even when treading water, 'Breaking Bad' still retains its intensity and sense of drama. But after the first three rollicking episodes, it was interesting to see the show take an hour to collect its thoughts and linger for a little while.
