You know, I would probably have liked the show a lot if it hadn’t been a BB prequel. The writing is fantastic (at least most of the time), the look of the show is great, and the characters are interesting. It’s just that Saul/Jimmy and Mike on BCS feel so completely off compared to their BB counterparts that it makes my head hurt. Especially Saul/Jimmy. Mike started out very interesting indeed, but now he’s pissing me off, too. Only *now *he’s getting into the crime scene? Like, a few years before BB, at the age of, what, seventy? It doesn’t even make any sense. The whole point of Mike on BB is that he’s a grizzled veteran, who has been around the block any number of times, and seen it all.
I’m probably projecting, but I’ve been listening to the BCS podcast some, and a couple of times Bob Odenkirk and Jonathan Banks have sounded exasperated in a way that almost makes me think they agree. Odenkirk said at one point something like “the fans are being patient with us, and if this show gets three or four seasons, then we’ll all see what it’s really about”. OK, maybe he didn’t mean: “Right now, it sucks”, but that’s how I heard it in my head. 
As for Mike, one of the writers was going on about how Mike “isn’t Mike yet”, that BCS is his origin story, too, and Banks basically jumped on her, explaining that Mike isn’t a newbie. He’s hardened. And you could just tell that he found it mindboggling that she couldn’t understand that.
Or at least, as I said, that’s how I heard it. Again, I’m probably projecting. Anyway…
Also, I can’t stand the constant references and callbacks to BB. I haven’t completely articulated why yet, but it’s like the writers are too much in love with BB, and not in a good way. I dunno. It ticks me off. It feels like bad BB fan fiction sometimes.
