Yeah, great episode. I'm impressed that they just went for it, full Breaking Bad style. They're establishing quite early that the show can have a multitude of tones. Which opens up a lot dark possibilities.
Some of the dialogue writing was quite weird, like it was going for realism but overshot. This was most apparent in Stacy's dialogue, which honestly might have been more convincing if she had an accent. Also, there was a particularly Yoda-esque backwards sentence uttered by the bartender.
I'm nitpicking, though. The power of Jonathan Banks kind of melted everything else away.
