All the talk about SGE has been really interesting to me. I haven't had the opportunity to see it yet, but I've been reading the negative comments for quite some time on a number of different sites.
I was a huge fan of AE, and I always felt rather alone in that, to be honest. Before SGE replaced AE, everything I heard about AE from others was negative. Some hated it for being too scary, others said it wasn't scary enough, and still others said it was incredibly "un-Disney." Now granted, at the time I wasn't a member of any Disney fan forums, so that sentiment might not have been shared here. But we are really in the minority compared to the number of casual visitors at WDW who don't spend their time hanging out on WDW fan sites.
The concept for SGE must have sounded terrific on paper... take a heavily-criticized attraction and re-theme it around a popular character from a kid-friendly movie. If you had asked me, I wouldn't have thought that a massive budget would have been necessary to successfully make the change. I didn't like the idea, because I had sentimental attachments to AE, but I could appreciate the reasoning behind it.
To be honest, I'm really surprised that SGE has gone over so poorly. But then, I haven't seen it yet myself, so I can't really offer an opinion of my own. From what you all have said, it sounds like it could use an improvement.
I'm sure that Disney is listening and will respond if they receive enough complaints. Think about JII. When the old ride was experiencing major technical problems, they decided to completely redo it and re-theme it based on the new concept for the Imagination pavilion. After the new ride went over like a lead balloon, they reworked it again. It's never going to be what it used to be, but at least they improved it based on guest feedback.
Us die-hard fans tend to get really attached to our favorite attractions and have a lot of trouble letting go when they get demolished due to structural problems, failing technology, or just changing times. But sometimes we let that get in the way of common sense. (It boggles my mind to hear people tell Disney to "move" an attraction to a different park or "bring back" a demolished attraction, as if it were so simple!)
I would highly recommend that if you don't like SGE, you make some specific suggestions or comments about it (e.g. "I felt like the ending left me hanging; it needs a stronger finish" or "I found the chili dog smell to be too strong and very offensive") and put them in writing. While it's definitely possible that Disney execs hear about comments made on internet forums, written letters carry much more weight.
I'd be interested in hearing any responses anyone might get from Disney regarding their comments on SGE. Who knows... maybe we'll see an improvement in it in the future.
