I really liked the momentum at the end of Season 1 but it felt almost entirely gone at the beginning of Season 2. After struggling through almost ten episodes I decided to ask a friend if it was safe to just skip ahead.
It was the best decision!
After a few episodes it was obvious which direction they were taking the main storylines... they just needed to hurry up and get there!
Episode 19 is where things really start picking up. The main team is finally back together to run an interesting operation and then the episode ties into Age of Ultron also.
At this point I'm starting to realize that Agents of Shield is best when it's tying into the greater MCU and at it's worst when it's biding time. I really hope that Season 3 finally has better pacing when I give it a shot.
