I didn't know they were working on a spin off. I liked Saul's character, including his dressing style, and the hair...oh my, the hair. I've known people who look like him, they're usually downtown, 5:00 rush hour, waiting on the RTA at the busiest bus stop. All sorts of far out characters are found there : )
I can't imagine how they can develop his character, I guess I will have to wait and see.
