The only ones I really care to watch are
Iron Man
Avengers 1
Gaurdians 1&2
Infinity War
Never cared for the CA or Thor films. Or Ultron, Etc.
For me, iron man 1 was the best story. Avenger 1&3 and the guardians movies gave the best adventure and spectacle. The incredible hulk was...okay.
The rest, I could take em or leave em. I can't even tell the difference between civil war and winter soldier. They just all look and feel the same to me.
