Avatar actually fits perfectly at the park, and has ZERO connection to the movie's characters. Flight of Passage is completely different as you are pushed into the screen, so you are essentially 100% surrounded by the screen. It also has a motion base more akin to Simpsons, and the queue, land, and visuals are so good you forget you are about to ride/riding a simulator. Not to mention the effects throughout and that it is a unique type of ride for the park. It's ironically better than every single one of Universal's combined

Why don't you go back to Disney World for the 50th, and see if you'll be so sad as a Disney fan. Yes, I understand you're not a troll as it is troubling how Disney has changed something that you care about so deeply, but as a fan to never want to experience something again is actually overkill. Especially if many changes like Pandora, TRON, and Star Wars have no faults as far as placement. GMR being replaced, and EPCOT Center as a whole is what's changing, but part of that is also linked to changing what the parks stand for. They're evolving, maybe not the way we like them, but they are getting quality additions. That's a big deal, and if you can afford it, why not check it out to see if they're different, but also pretty awesome. Maintenance is far superior to what it was a few years ago, and there will be loads of new rides.
