What they ought to do is just remove the roof off of the theater and turn it back into the Tomorrowland Stage. They should have some big name bands playing there on the weekends.
I say we should create a petition. Just talking about it here will get us nowhere.
I would like to see Alien Encounter replace Captain Eo. I got to experience Alien Encounter back in 2001 and while I did enjoy it, I thought it was more tame than it was hyped up to be. I wasn't terrified like some maze at Halloween Horror Nights, it was just fun effects that lead to laughs. The terror of AE is overly exaggerated. So yes, bring it here with out the Stitch overlay.
I really like the attraction for the futuristic technology that it showcases and how it actually does something to compliment the theme of Tomorrowland (unlike its current residents consisting of cartoon fish and space man toys)-- most prominently the teleportation aspect, a highly futuristic concept that we have not yet come close to achieving, but also the communication with extraterritorial beings. Perhaps one day we will find life on a planet other than Earth or that life will somehow encounter us-- we're always looking for signs of life on other planets and I think the idea of actually encountering it (or it discovering us) is a very futuristic idea. My main concern is that the attraction may be a bit too sci-fi for the good of the land. I'd really like to see some attractions actually based on scientific fact and progress to enforce the land's original message of the great, big, beautiful tomorrow that's just around the corner. Sci-fi attractions, although futuristic, don't really enforce that message. They showcase their own little world that seems so separate from ours. Their technologies and advancements and ideas, though indeed futuristic, are so far ahead of our own world that they assume an air of fantasy instead of a soon-to-be reality. And for Tomorrowland to be an effective land that really compliments the rest of the park, it needs to highlight the promises of tomorrow instead of being a realm focused on fantasy attractions.
Regarding the scariness level of the attraction-- I don't know, the Haunted Mansion shows us a dead man hanging from the ceiling while his ghost narrates our trip, we see the ghost of a murderous bride and portraits of all the husbands she has killed, we see undead creatures trying to free themselves from their coffins and graves, so it's not insane to think that Disney can still create mature attractions with dark elements. Granted, Haunted Mansion has that slightly whimsical feel with the ghosts singing and the idea of the mansion being a "retirement home", but there are parts in there that are still genuinely scary. So, is an attraction with a bloodthirsty alien still "off-limits"? Although Alien Encounter is definitely more intense than anything currently in the resort, I vote no, I don't think the "scary" factor of the attraction should be the deciding factor in this scenario, but rather, theme and story.
A final note-- I never got to expereince the original attraction but I think the idea is so unique and genius-- I would absolutely love to ride it if it ever did return. The idea of an experience that builds up the story with some background and then eliminates the sense we are most reliant upon to create its experience stimulating our other senses and evoking different feelings through the stimulation of those senses just seems so darn cool-- so much of what you feel and hear during the attraction is left entirely to the the Guest's imagination and interpretation, so much of the experience is really pieced together and created in our own minds with the cues of the various stimuli that the theater provides. This ingenious ride/show system, coupled with the fact that the futuristic ties could somewhat help Tomorrowland's struggling theme, would make me really excited to see this attraction come to Tomorrowland-- even if I don't really think it's exactly what the land needs.
As much as I liked Alien Encounter, it was something that worked better at WDW. Because it mostly takes place in the dark and doesn't have a high level of detail, it just isn't repeatable enough for the SoCal audience.
I would love to see Alien Encounter make it out this way. I remember the first time I had heard about it, I absolutely loved the idea. Disneyland can use something dark for the older audiences, and its not like it would be completely out of place, I mean DCA has Tower of Terror. The one trip I've had out to WDW I was able to go on the Stitch version, which was fun as I absolutely love the character, but it kinda hurt knowing I was far too late to go on it as I had always wanted.
