As much as I hate to admit it, it would've been very distracting. This show has no Walt to anchor it. Even with Walt, Gus almost stole season 4 of "Breaking Bad".
The way this season ended, we can speculate on just how different Jimmy and Chuck really are, because Chuck conned the fukk out of Jimmy in that last scene. We can wonder how that recording will fukk over Jimmy and Kim, on down to minor characters like Ernest and the copy shop guy.
You introduce Gus and all that shyt goes out the window. The focus would be on Gus. The way they did it with the DON'T note you know Gus is on the periphery watching everything going on, even if you don't see him. Once Gus is introduced the dynamic of the show is going to change drastically because he can't even interact with Jimmy/Saul.
Fred.
I don't think it will change the show, Gus will be interacting with Mike. And Mike hardly interacts with Jimmy/Saul. A lot of people are mistakenly thinking Jimmy and Mike are cooler than they really are, Mike is only out for self. We might not even see those people that were getting legacy payments and was killed in jail by those bikers.
Mike only needs Jimmy when he needs a shifty lawyer.
With Jimmy becoming Saul this is the best character study I've seen since Mad Men. But Mad Men did it with the whole ensemble, while BCS only focuses on Jimmy.
