OK, kudos to the guy who created this thread because this needs to get out into the open.
There are several reasons why there in the crossover hate manifested by various individuals. It will vary from person to person. These include:
1: Fear from rival organisations in Hollywood. Make no mistake this project from MARVEL studios is a major THREAT. An upstart rival company has come up with an innovative concept that has the potential to become an incredibly huge financial powerhouse. This shared cinematic universe has the potential to develope a tremendous consistent dedicated moviegoing fanbase that could put other franchises in the shadow. It's obvious the potential is enormous, which is one of the reasons why DISNEY purchased MARVEL. And the project came gangbusters right out the gate with a mega-blockbuster in IRON MAN. Rival companies fear this and will have representatives out there trying to shoot it down through bad press. Make no mistake many movie reviewers are not objective but have hidden ties to studios and will try to serve their ends.
2: DC fanboy jealousy. Flat out there are many, many, many DC fanboys who are very jealous of MARVEL's success. Some wish DC/WB had come up with this idea first and since they haven't they try to shoot it down. For some other DC fanboys it's simply trying to bring down MARVEL's success in some way or the other. They can't say that the movies are crap. They can't say that the GA hated them. They can't say that critics destroyed the movies. They can't say that the movies bombed at the box-office. So what do they have left. Really, nothing, but they try and make up some crap. So they criticise the MCU concept, and they yammer on about how MARVEL movies only 'play it safe'. It always fails but they keep trying.
3: Resistance to change, like Kedrell said. This is a new and innovative cinematic concept. There will always be people who resist new, outrageous ideas and concepts.
4: The Dark Knight effect. TDK has made a tremedous impact on the minds of many people. I'm baffled as to why because it's truly the most overrated crap movie of all time. However Nolan did a superhero movie a certain way. It's the only thing DC fanboys have to hold onto so they put it on a pedestal and criticise anything different. Understand this: Nolan does not give a damn about the DC comic universe. Batman was a career stepping stone for him, nothing more. His TDK franchise has sucked all the fantasy and mythos out of Batman. He took already the most GA relatable and (2nd most) iconic comicbook character and took all the 'comicbookyness' (no batmobile, batarang, etc., etc.) out of it, giving the world a crime drama that even more of the GA can relate too. MARVEL studios is different. They LOVE their comicbook universe and respects their fanbase that also loves that universe. Thus they want to put that universe up on the screen for their fans and hopefully to develope more fans in the GA. THEY ARE DIFFERENT. So Nolan-worhippers see something different from Nolan fantasy-less stuff and abhor it.
And there you have it. A couple other quick points:
- TDK did not get nominated for best film because it WAS NOT WORTHY of being nominated, nothing else. Geez, Nolan-worshippers, please over yourselves and off this guys d!ck.
