Hopefully they'll have some of the memorable Breaking Bad characters just walking through, or maybe getting involved, from time to time. I mean let's face it... Skinny Pete and Badger prolly aren't real busy these days. They could even do it kind of Lost/6 degrees of separation style, where Saul had been in the same line with this or that character at the grocery store, laundry mat or gas station... well before he ever got involved with them when he came onto Breaking Bad. Maybe not Walt or Jesse, but I bet some of the other characters/actors would do it.
This could be really cool & funny. Or it could be just a dumb rip-off. I'm hoping they use their brains and make it cool & funny.
