Like one of my favorite marvel comic runs in recent memory was Matt Faction did Hawkeye indie comic style where he was just a dude owning a brownstone in bedstuy dealing with neighbors. etc...with the big plot being him balancing out a fuck buddy type relationship that leads to a breakup (for the big breakup the issue took place from the dog's perspective).

While you can play with different action/suspence genres types (Borne identify spy thriller in Winter Soldier, broad comedy in Ant-Man, I expect a marvel horror film eventually) the fact you've gotta have big action set pieces is kinda of a detriment to those kind of simpler stories.
