I guess a lot depends on what you expect from the attraction and that can vary from person to person. I like to be entertained more than thrilled.
I agree with everyone about Journey into Imagination. The original was great, but the subsequent versions are not even good. The first remake was awful and the last didn't even come close to the original.
The Swiss Family Robinson Treehouse was only mildly interesting the one time I saw it.
Sounds Dangerous just doesn't cut it, even for me.
I'm probably alone in this one, but Fantasmic left me less than impressed as Disney shows go.
I agree with everyone on the Grand Prix Race Cars. They just seem out of place in an upscale park.
I haven't seen Stitch's Escape, but Alien Encounter was a bit extreme and Mission to Mars was very lame, so I'll assume the worst.
I'm more frustrated with so many good attractions that have been eliminated or changed.
