For me, it’s Captain America: The Winter Soldier.
The plot is pretty intricate, like a comic book spy thriller with lots of twists and turns. The part where SPOILER Nick Fury gets pinned down by bad guys while his car AI is rebooting is particularly intense.
My second favorite would have to be Captain America: Civil War. I guess I’m partial to Captain America movies.
