Fantastic episode, guys. I'm in pretty complete agreement with Dorkman (and also Trey, except when he says you could get away with just randomly having the kid be a superhuman killing machine). I love Rian Johnson's other work, the trailers for this were great, and I was expecting a total home run. Turned out to be just okay. I'll probably never watch it again either.
I just couldn't manage to make it to the theater on this one, so my first viewing was on the blu-ray from Netflix last week. Since I had the option I watched the bonus features too, so I wanted to address a couple of things you guys touched on. First, in regard to Kid Blue being Jeff Daniels... If you consider deleted scenes canon, no.
You could argue that in the theatrical cut it's ambiguous, but Rian Johnson's intent in the film as scripted and filmed is just that Blue's a screw-up of a lacky who looks up to Daniels' character. There are a whole host of deleted scenes featuring Kid Blue, and how he tracks down the Joes. But the revealing one is after Daniels takes his gun and hammers him, a guy takes him out back and is going to kill him, but Kid Blue escapes. So safe to say he's not meant to be young Jeff Daniels.
You also mentioned that it's surprising how wonky the time travel mechanics are, because he had Shane Carruth consulting on that, but Johnson makes a remark on that in the commentary. Towards the ends he basically gives him a thank you shout-out and says, half-jokingly, "He looked over the script and said, it's good, but your time travel is total bullshit, and then I didn't do anything about it." I'm paraphrasing, but not that much.
