Even Nolan's trilogy had a great sense of idealism with statements like anyone can be Batman and make a difference. Many are rejecting Snyder's assertion that the real/flawed world would be no better with superheroes, and furthermore they would unavoidably be a product of the real/flawed world. Therefore, any idealism will be met with controversy and conflict. That is how the way the world is, but some people what pure escapism whereas others appreciate acknowledging how things really are. I want to see Snyder direct X-Men. Snyder does have flaws as a director but so do most superhero directors, which is why TDK is still lauded at the top of the genre. Yet, people are using any opportunity to push their aesthetic bias by conflating anything negative and use any opportunity to assert it's the approach that's the issue.
