And the implication there - which is completely justified - is that they can't have what they're asking for because it's not good enough. It's not sophisticated enough, not ambitious enough, not entertaining enough to impress or attract a new audience.
But that's the erroneous notion that upsets many of those who didn't like the movie. Most people who like the movie (including the writers of course) present it like it was the ONLY possible solution. Which isn't true. Can't be proven, though, since nobody else is capable of trying, or will be allowed to try.
And if the next movie gets better, you will see that many who hated this movie will change their mind. Because right now, it just seems that the next movie will be exactly like this one (and that the writers think and say "We don't care because there are so many other people who think otherwise." to those who didn't like the movie). That upsets a
fans (as in fanatic) just as much as it would upset a homeless person when a politician says: "Listen, I don't care, because 250 million other people have a home."
And ironically, if the next movie gets worse, you will see that many people who vividly defended this movie will turn around and suddenly say "I saw it coming."

That happened a lot of times already in the history of movies.
