This came on while I was channel surfing the hotel TV and I was immediately hooked. Two years removed from the hype it's as great as experience as it ever was. I was riveted through all of Act 1-3, great character interactions, emotions, and humor, and when the action does finally come it absolutely delivers with some of my favorite scenes in any movie. The pinnacle of the MCU. A+.
Also one new thing I noticed was that this might be the funniest MCU movie. There were a lot of good and memorable jokes and yet I hardly ever felt they detracted from the emotions or the sincerity of the movie. Very well balanced in that regard.
