Avengers Endgame. I loved it. A great way to round out phase 2 of the MCU and retire the characters that have been with us from the beginning.
I loved the sadness of their failure from the last film, the hope that they might find a way back, the callbacks to the previous films, the final confrontation and resolutions to so many characters arcs.
I'm not ashamed to say I got a little emotional as I was cheering them on. I loved these characters as a kid reading Marvel Comics, and I've loved watching them reincarnated in the MCU. I feel an endpoint was reached, and a new story is starting.
