The pacing has seemed really poor this season. Spoilers ahead:
Like a few weeks back, the episode ends with Gyp Rosetti nearly getting assassinated, a bunch of his bodyguards killed, and some gratuitous dongage. You expect, hey, next week shit's really going to hit the fan, right? And then, BOOM, they don't even MENTION Gyp Rosetti in the next episode. What the fuck? They did the same thing with Eli; he seems to be getting a legitimate story arc, he's making a comeback, BOOM, let's ignore him for an entire episode. I'm liking the political intrigue and Nucky's ongoing dealings with Milton/the Attorney General/Mellon, but they keep skipping a storyline for a week to focus on something they haven't mentioned in a few weeks, then ignoring that to skip back to the original story in the next episode; it's just disjointed.
It probably doesn't help that the show encourages the consumption of whiskey while watching it. My memory gets a little fuzzy on what exactly has happened and when.
