I think the key is to go in with moderate expectations. I like it so far.
The brother is just a vehicle to drive Jimmy away from pursuing a prestigious law job. He doesn't want to end up like that/wants to make his own name. I.e. Saul
I don't think the brother will serve any other purpose.

Lewis Black was great in his limited role on the show. I'm with you. It would be brutal to see him every day.
I think maybe a non-baseball Point/Counterpoint...?
