No...some fans want a good movie because filmmakers should focus on making a good movie each time they make a comic film, not just saying "hey, we'll just make a good movie next time." Absolutely terrible mentality.
Not really. Many consider BB and TDKR just as good, if not better than TDK. All three films are considered great. And interestingly enough, Nolan took the approach of trying to make the best film he could for each movie.
Not everyone will be satisfied....but that dosen't justify making flawed films, ones that could've been great. I mean, are you serious? Are you really trying to justify getting "Amazing Spider-Man" type reboots? LOL.
Golly, if only Peter Jackson and George Lucas knew that the best way to an epic trilogy is by making a first film of questionable quality.
