You crap on a lot and most of it's justified, but Civil War is a fun movie. Worth seeing if you like these movies.
That said, it's pretty undeniable that the Marvel Studios films are both very popular (with a diverse number of people, not just comic fanboys) and generally very well received by critics. That consistently is pretty remarkable and commendable for a film studio, especially given how hit or miss comic book movies tend to be (and how the Hollywood elite tend to frown upon them). You'd have to be a pretty cynical person to not appreciate the work that Kevin Feige and Marvel Studios has done in their existence, even if the movies are not your cup of tea.
