There's truth to the notion that fandom hasn't changed. There will always be criticisms thrown at any new Trek film, both good (TWOK) and bad (NEMESIS). Old letters criticizing TWOK for "destroying the franchise" doesn't automatically mean that STID must be good since it gets the same noise. Every Trek movie seems to get that from a vocal group for various reasons. I don't pay attention to that hyperbole because Trek has been around for nearly 50 years and is likely not going away. I don't like the current state Trek is in, but I'm still optimistic for the future because I know that Orci/Kurtzman are not going to last forever.
