I agree that sadly, the anti-hero seems to be the norm.
What he doesnt want is to watch The Dark Knight and see Batman struggling with whether he truly wants to help people.
I didn't see Batman as conflicted at all.
Now, in the film adaptation of LOTR, Aragorn was portrayed as rather conflicted and unsure of himself, which I thought was completely wrong. In the book, he does not question his role at all -- although he does at least once kick himself for not always making the right decision.
