I finished Season 1 of Breaking Bad last night. That was a great first season, and it's showing how you can do character development on a limited number of episodes. Each episode has done a great job meeting the characters and showing Walt's transformation, to the point where what he did in the penultimate episode of the season was bad ass. I have to say though I'm not entirely a fan of Skyler yet. The episode with the Intervention kind of turned me off from her. It seems like she wants to make all the decisions for Walt, and Walt's response of this was the first time he's had to make a decision was spot on.
If you haven't watched Saul (yet), you may like it even better than BB.
With BB, the producers were on a bit of a learning curve, and still feeling things out as the show developed.
With Saul, having had that experience, they fell into a groove, operating like a finely-oiled machine. In some ways it's better than BB, and even more about character. I was skeptical about the need or want for a prequel, but this is one of those rare cases where it worked.
Saul has been shooting its final season, but probably won't air until '22, which sucks. Bittersweet.
