Almost all the moments mentioned got a pop in my theater. It was a saturday noon Dolby Cinema screening. Everyone in that room had bought tickets a month in advance.
I know someone mentioned it mockingly, but the moment when all the women linked up for a charge on Thanos, some chick in the room screamed "Come thru sis !!!" as they rushed him and everybody laughed and cheered. On your left, hail hydra, avengers assemble, Iron man securing the W, all the trips through events of the old movie got nice reactions.
RDJ's final credit picture got a standing O. I loved watching these movies with fans, made it crazy memorable. Seeing Cap and Peggy get their happy ending actually hit me the hardest emotionally.. Made me want to go rewatch Agent Carter.
