Tough.
For me, it's between TDKR, WW and Joker.
It's a bit easier to answer performance and characterization at this point than influence and impact.
It's still too soon for me to say which of the 2010s films will be influential or impactful. I don't think enough time has passed to really judge those things with TDKR, WW or Joker.
WW is certainly a landmark in terms of female led superhero films. Yes ,there were others long before WW , but none of them were cultural milestones they way the first WW film was. I suppose we can assume that other female led superhero films will follow and that the WW films may inspire execs to tell more female led superhero films.
The Joker certainly opens the door to villain focused films , even though it wasn't the first villain focused film. So in that respect the genre may expand, assuming other studios take that route.
TDKR certainly has made Bane a pop culture figure, but I can't say at this point whether TDKR in itself, as opposed to being part of a trilogy, has influenced or impacted Hollywood or the cbm genre.
Which is the best based off of performance and generalization?
For me, it's a coin toss between WW and TDKR.
I would probably have a different answer depending what day you asked me.
