Although I would agree that a lot of people on this board are not fans of it, but, so far I have yet to hear a solid reason for it other then they want to stay in step with the "popular kids".
It's a fun attraction, that is different then the ones that everyone is used to. I suspect those that don't like it were "Alien" fans and haven't forgiven Disney for removing it. How is there ever going to be a consistent narrative when the entire concept is made up and not even venturing close to reality. Even if you are talking about the fact that they have depicted Stitch as a problem instead of the "lovable" creature from the movie, it is explain that this would have taken place before that time. Low ratings do not necessarily mean that it still isn't the minority that doesn't like it with the passion that is displayed on these pages. I don't think that it is the most popular attraction at WDW, but, that doesn't in any sense of the word mean that it is a majority reaction.
I don't even mind someone saying that they don't like it, but, that chili burp reason is as bogus as one can possibly come up with, especially when it is coming from adults. That just tells me that those people need to loosen the sphincter just a touch.
