Dark Knight's biggest failing is the fact that it is a Nolan original script and does not adapt a comic.

Batman Begins was so successful because it adapted the best batman comic ever by Frank Miller, Year one.

Uh, for those of us that haven't read that Batman comic (and didn't even know it existed), BB was so successful because it rebooted the franchise and returned it to what it should be: a dark toned movie about Batman instead of the Schumacher crap we were fed for a few years.

Judging from the reviews and box office, TDK's failing is that a few people don't like the direction it went in.
