Yeah, it definitely ends with a thud. Though, I'm not sure what a satisfying ending would be, outside of some Tarantino-esque ish.

I would have liked both sons murdered relatively earlier in the episode and I wanted to see both fathers arrested in a dramatic end of episode montage. I wanted Michael's girlfriend to be the one who led to his arrest. They started down that road but either ran out of time, money, or interest to see it though. I think episode 6 or 7 could have been either cut or consolidated, episode 10 could have been 9, and 10 should have been the fallout from episode 9. Michael dealing with his girlfriend, mother in law, the detective, and the dude from the wire. Tommy with his wife, his daughter, and the detective, and Carlo if not killed off in episode 9.
