Okay, then, let me comment directly on the Stitch attraction.
First of all, it's called Stitch's Great Escape. From this many people infer that it's a kid-friendly attraction, since Stitch is a kid-friendly character. I sure thought so when I heard that Stitch would be replacing AE. But that's a falacy - it's dark, it's loud, and it's scary, just as much so as AE. "How could a cute little blue guy like Stitch possibly be scary?" many people think, and so they go in without reading any of the warnings, and little kids wind up getting scared.
Next, the storyline is not well fleshed out. As one of those folks who has not seen Lilo & Stitch, I was unfamiliar with any fo the characters except Stitch himself, completely confused by the plot, and puzzled by the fact that the animatronic Stitch had 6 arms. I thought Stitch only had 2 arms - was that Stitch, or his cousin Mitch? I had no idea what was going on.
It's LOUD. I found the 'cannon' shots to be terribly loud, almost to the point of pain.
And finally, the chili dog burp is not only disgusting, but sickening. The smell actually makes people nauseous, including me.
So basically, A) I hate that they took away my favorite Tomorrowland attraction, and B) I hate that they replaced it with something that is so cheap, flimsy, and cheesy that the old XS Technology logos weren't even taken off the walls during the makeover.
