The two plot storyline works on all levels.
The way they gently intermingle is genius. The hardcore drug dealing theme mixed with the creative lawyer theme is priceless. Saul is the perfect character and nobody could play him better than Odenkirk. Saul is funny, gritty, intelligent, lovable, and flawed. Mike, played by Jonathon Banks, is soooo bad ass. I love everything about this show.
