You constantly mention this video as though Disney employees are speaking spontaneously when doing those very sort of talks. They're scripted and approved. Just because Joe is engaging is no indication of how he feels about the park. Selling the idea is part of his job, whether he likes it or not and there were plenty of stories that if he didn't like it he would be finding himself joining the likes of the Kirk brothers, Delaney and Baxter. A good counterpoint to a Disney produced film would be Joe's relatively recent appearance on The Season Pass Podcast from last year's Thea Awards where Avatar is rather glossed over, but again as an arranged interview at an industry event it is still impossible to declare it a true reflection of personal feelings.
