Looking back both of the Avengers movies were pretty lack luster imo. They were good action popcorn flicks, but that's really all they had going for them outside a few moments with each film. Not saying that's a bad thing, cuz they catered to an audience that appreciated that and banked. Whenever the Dark Knight is on television I tend to not change the channel.
A better movie to compare TDK is Winter Soldier. I'm appreciating that film even more now that time has passed

.
Civil War might top that, but I feel like they might be trying to do too much in that film. That's for another thread,
but I hope I'm wrong.
