Well, the latest episode wasn't horrible. It was still bad but not claw your face off bad. They did pull a bunch of shit out of their ass though. Betsy Ross and Mills' father to hit the highlights. In the process I think that they have now tripled the original cast. That isn't necessarily a bad thing but given their track record so far, it probably will be.
It almost looks like they're gearing up to do a spin off but that can't be the explanation since at the very least, I'm sure this show is going to be on the bubble for next season. So my best guess is that they're going to use the spaghetti approach to revamping the show in a desperate attempt to avoid cancellation. IOW, they're going to throw everything they can think of into the show and see what sticks. Like this approach has ever worked for any show . . . ever.

edit: Oh, and I just thought of this. As I was running the cast members through my head I realized that with the sole exception of Crane and now Betsy, the entire cast is black or brown. I hate to be so cynical but this would seem to be a blatant attempt to pander to a minority audience. I can't imagine that's going to work, but I guess we'll see.
