I have read some of the reviews and that is the consensus. While the Avengers is good mindless fun, TDKR is on an entire different level. I think Nolan is raising the bar once again for superhero movies. You can have great action with a deep and engaging story.
Yeah they are on a different level, and these have been some great movies.... but I still don't know that I would call them my "ideal" kind of superhero movies.
I'll always prefer the more fun and fantastical ones like Avengers, Batman, and Spider-Man myself.
