You really don't like the Russo's movies? Winter Soldier is probably my favorite Marvel movie so far. I honestly think if it wasn't for them, Marvels ship might have sunk in phase 2.
I think it's a good run time because there is a lot that needs to be addressed in the film. And I will be watching this Thursday night and reading draft results when I get home. We probably trade down any damn way.
winter solider i thought was ok but fundamentally could have been a lot better with some fairly simple changes
civil war and infinity war would probably be pretty low in my ranking
this video has some interesting thoughts on the russo brothers films - and makes a lot of points that i agree with on why their 3 films dont really engage me in the same way many of the others do... not saying this is the be all and end all of their films and others are entitled to disagree but i find myself very much aligned with this video's take: the section on the russos as directors in the MCU starts at 9:44 and ends at 15:44
although if you're interested i would recommend the whole video (and the others in the series he's made)
honestly the MCU would have been fine without winter soldier - financially it made the 3rd least of all the films in phase 2 (only ahead of ant-man and thor: the dark world)
and while this is subjective i will say that it's probably indicative that the Russos helmed my 2 least favourite of the phase 3 movies also...
