I'm generally pretty against prequels since 95% of the time they turn out terrible. This has started well though and I'm looking forward to watching more.
I also thinks it has the potential to be better than Breaking Bad. BB had some great, absolutely brilliant episodes and story arcs, but it also had a lot of crap ones and filler mixed in, and some pretty cringe worthy characters. So easy to forget those looking back. It also took a while to find it's footing. I think Gilligan will have a much clearer vision going into this project, and probably have a lot more leeway on what he can do, and many of the characters are already developed.
