I'm going to try to squeeze in a viewing of Agents of S.H.I.E.L.D. Season 1 on Saturday, September 13. The show, of course, is 22 episodes long, which makes it roughly 18 hours long. Further, there's a movie that takes place about 2/3 of the way through the season that, while it doesn't directly involve the characters from the show, has a strong impact on the characters in the show.
Do you want to watch Captain America: The Winter Soldier in its place in order?
Do you want to watch all of Season 1 or just the good parts version?
