That's not to say that all movies in this category are *only* worth watching in the theater like Avatar is. For instance I would have still enjoyed the recent Dune movies either way but they were a lot better with all the pomp & circumstance.
Or maybe it's just a horror/Marvel thing. Weapons and Endgame had a similar audience feel to Sinners and Black Panther.
Definitely not during Chris Nolan films. It's hard enough to hear his dialogue when it's dead silent.
