While I'm not crazy about Stitch either, I would say if there isn't a line, do give it a try.
It is a shadow of AE, so if you can imagine a preshow with intergalactic used car salesmen...no, more like political spin-masters mixed with a little bit of Ron Popiel, instead of the galactic prison guard thing you have a start.
Then in the show chamber, picture instead of an annoying Stitch that isn't anywhere near as clever as in the movie, that talks and laughs incessantly to convince children that there is nothing to be afraid of, a large alien (as in the movie Alien) who is truly a predator stalking you while you're trapped in your seat, eating a few guests, and coming very close to you in the pitch black...
...you have it.
