TDK isn't the first crime/serious comic book movie either. you could say the first batman movie in 89 did that. or v for vendetta. or road to perdition. or numerous other examples.
I didn't say it was. BB was also a crime/serious comic book movie. The first Batman didn't defy the genre, it defined it. At that point the only real commercially viable comic book film was Superman, which had been years earlier. When Burton's Batman came out, there wasn't much to compare it to in terms of the comic book genre. By the time TDK came out there was five other Batman films, three Spider-Man films, a Daredevil film, two Fantastic Four films, three X-men films, etc. You get the point. People had a preconceived notion of what superhero films should be, TDK took that and twisted it on its head, even more than Begins did, and while doing so it managed to become one of the biggest movies of all time.
Also, V for Vendetta was a well received film but it didn't make even close to what TDK did at the box-office. Does that make it an inferior film? No, but it makes it a lot less popular one. As for Road to Perdition, 90% of the people who saw that movie didn't even know it was based off a comic book, so, that argument doesn't hold up much weight.
and the outrage that it didn't get a best picture nom? from fanboys? who cares what they say. it wasn't best picture worthy.
Not just from the fans. From critics all around the world who hailed it as one of the best films of the year and cried foul at the Academy. And guess what? The Academy listened and expanded the number of best picture nominations the following year. One of the most well reviewed films of the year and dozens, if not hundreds, of critics saying it got snubbed? As Gordon himself says, "you can't just sweep that".
it's a great movie, one of my favourites. but defined the genre? put it on the map? don't make me laugh. it was a great action/crime thriller that happened to feature comic book characters. that's it.
The Dark Knight is the only movie I know of where people who don't even like to go to the movies went to see it multiple times. It was a phenomenon. I wasn't around for 89's hype and release, but if it was half as amazing as TDK's, it must have been spectacular. Find me another superhero comic book film that had the same effect as TDK before TDK, I challenge you. A film that critics called foul at the Academy for not nominating, a film that made over half a billion in the US alone, a film that aclaimed, award winning directors like Sam Mendes have said:
"It was a game changer for everybody... what Nolan proved was that you can make a
huge movie that is thrilling and entertaining and has a lot to say about the world we live in... That did help give me the confidence to take this movie [Skyfall] in directions that, without The Dark Knight, might not have been possible. Because also, people go, Wow, thats pretty dark, but then you can point to Dark Knight and go Look at that thats a darker movie, and it took in a gazillion dollars!"
I don't care if you hate or love The Dark Knight, to say it didn't make a huge impact on the genre and on movies in general is being really, really daft.
