P.S.
I just had a go at ranking them, and realised I was well into the bottom half and still looking at movies I love! That's so cool. Even the lowest ones for me are just kinda 'meh'; I don't dislike any of them.

Here's what I came up with (and I'm re-ordering it in this comment window!):

GOTG
Avengers
Dr Strange
Ant-Man
SM: Home-Coming
GOTG2
CA: Civil War
Captain America
Iron Man
Thor
Iron Man 2
Avengers: Age Of Ultron
CA: Winter Soldier
Thor 2
Iron Man 3
Incredible Hulk
