Avengers: Endgame

Mine is also Winter Soldier

Black Panther

Captain America Winter Solider

Thor:ragnarok probably

ENDGAME FOR LIFE 🔥

Just an idea - a good way to ask this question and get a more diverse set of answers might be 'what is your favorite non-Avengers movie'... it's pretty tough for the solo films to compete with the big crossovers, even the most popular 'solo' films are actually ensembles (Ragnarok: Thor, Loki, Valkyrie, Hulk, etc. or Winter Soldier: Captain America, Falcon, Widow, Fury, Bucky, etc.)

I like that idea better @Fiona225. I’ll say:

Non-Avengers film: Doctor Strange or Captain Marvel (if we’re not using Avengers/mini Avengers films).

Avengers film: Of course, Endgame. I really do enjoy AoU though even if people think it’s the worst Avengers film; Engame still blows it out the water.

Don’t really have a favorite because I like them all
