That's just it, there's no creativity in Hollywood. What's unfortunate is moviegoers are fueling the problem. As usual in this modern society of garbage, money trumps everything else. You'll never see a Duncan Jones movie make a billion dollars, but you'll see Transformers make it. I like what Duncan Jones has done, his first 2 movies have been well done creative pieces but haven't got hardly the recognition they deserve. People like Michael Bay on the other hand, well his garbage speaks for itself. Sequels are given the go ahead after opening weekend, sometimes opening day...that's a little ridiculous.
Quite honestly the only movie I've seen that had a shred of creativity that made a lot of money was Inception. However that made money for the wrong reasons. 2 reasons in particular...Nolan fanboys (yes I'm going there

) and legitimate lack of intelligence and attention span. People went into the movie expecting a "mind f*ck" or a "blow your mind" movie, and quite honestly most of them got it which is incredibly sad. People today as a whole are incredibly stupid. If you paid attention to the movie, everything was fine. That's the problem, you have to pay attention. People don't know how to do that anymore.
Good films that could have great sequels are getting shoved off while mindless, cliche, boring, unsurprising and predictable, recycled crap is being made again and again.
As for the Tarantino movies though, I can definitely understand why people don't like them. Your reasoning speaks for itself. His movies are the definition of acquired taste. I don't mind them, some are hit or miss, but I certainly wouldn't put his work at the top of my favorites list. I do think he brings a respectable level of creativity to the table though.
No one cares about quality anymore because quality doesn't being in the cash.
