It would be sad if you felt nothing after that three-hour run (besides perhaps an urge to pee, or irritation with your fellow moviegoers, if you too had to sit next to an extremely loud laugher whose guffaws drowned out most of the post-joke lines).
Since Avengers: Endgame is playing on a record number of screens, fans who’ve already seen the movie in sold-out showings are already managing to get tickets to return.
It’s the end of an era, and it’s good to feel that.
