This and Captain Marvel are the only two MCU movies I’ve paid to see while they were in theaters. Both late enough that there were only a dozen people in the audience. (I also saw Black Panther and Spider-Man: Homecoming on a big screen, courtesy of the CWRU Film Society.)
Just gonna leave a block of spoiler-space and then jump right in.
(I have a non-spoilery Infinity War post over here, too.)
