I write this with "Lilo and Stitch: The Series" playing in the background, so maybe I'm a bit biased toward the current occupant of the former Alien Encounter building. In any case, I still feel that Stitch's Great Escape is a much better attraction than Alien Encounter. I'd like to try to respond to a couple of the arguments against Stitch:
1. The attraction doesn't follow the plot to the movie or TV show. True, however, let me just point out another attraction - considered a classic by most, including myself - that doesn't logically follow the movie it is based on. I speak of Star Tours, based on a little series of movies you might have heard about. It revolves around a trip to the Endor moon, which just happens to have another Death Star around it. Now, we know the events of the attraction take place AFTER "Return of the Jedi" because R2-D2 and C-3PO are discussing their previous visits to the locales on the large screen behind them (Endor, Hoth, Tatooine). However, as mentioned, a Death Star once again resides near the moon of Endor. This Death Star, surprisingly, has the same fatal flaw as the first one from "A New Hope," namely a thermal exhaust port. So, you're attacking the Death Star from episode IV in a story set after episode VI. And, most interestingly of all, they're running a tour company around areas the Empire is currently occupying. Very bright. But, guess what? It's a ride! Suspend your need to overanalyze things like I've just done and enjoy it!
2. The chili dog burp - Okay, if this is your biggest complaint, I would advise you to stay away from "manly men" (who tend to burp at the drop of a hat) and many of the tourists around you. Both can be far more disgusting than anything pumped out in a Disney attraction. The chili dog smell doesn't bother me, and I noticed no lingering after-effects. I would think the stink bug smell from It's Tough to be a Bug would offend more noses. I'm fine with both, as they are humorous touches to the shows and as mentioned, the smell fades quickly away (at least it always has for me).
Then there's that argument about how did he get a chili dog from someone when there's no food or drinks allowed. Surely you don't believe everyone listens to those warnings. As a former cast member, I KNOW people sneak things in places they're not supposed to. If you need a logical explanation how it got in there, the person got in line, put the chili dog (from Casey's Corner, as mentioned in a previous post) back into the aluminum foil-ish wrapper it came in, carried it with them into the attraction (out of the sight of the CMs), and placed it on the ground next to them for the attraction. Stitch smelled it, went after it, ate it, and burped it. Problem solved.
3. Alien Encounter had a better story - To some, this may be true. I always felt it was seriously lacking...Sounds Dangerous with restraint harnesses (but not as humorous). The whole point of it seemed to be to subject people to unnecessary amounts of gore (spurting blood) and death. And the ending was the oh-so-positive "let's blow up the alien" and spurt the audience with more water/simulated blood. Dare I mention how lame the Alien actually looked when you could briefly make it out? That was a supreme disappointment to me after seeing the incredible SIR and Skippy preshow. Finally, I always felt THIS show ended much too abruptly. Blow up the alien, oopsy from Kevin Pollak and co-worker, then get out. No happy ending, no retrieval of Chairman Clench (probably also dead), just a blown up alien and lots of "now dead" guests. Wow, that left me feeling uplifted!
I mentioned this in another post, but I think it warrants mentioning again - I didn't hate Alien Encounter; I just didn't think it lived up to its preshow. I also think it would have fit in much better at the Disney-MGM Studios, which has always seemed to have a bit more of an adult focus. The Magic Kingdom's Tomorrowland just felt like the wrong place for something so lacking in a joy and inspiration. At least the end of Stitch's Great Escape has Stitch escaping to be his mischievous self. No one dies. No blood. No gore. I know Alien Encounter seems to have inspired some. I just wasn't one of them, once SIR and Skippy were done.
