i have also read this on another website (wdwmagic.com) also I saw the show the week it first came into the parks. i didn't know what to expect when i was waiting for the show to start.
There were a few things in the show that i liked that related to former attractions in tomorrowland such as the timekeeper and alien encounter which i found fun. the story is basically set on galaxy day or something like that but i didn't really understand where stitch came in, it made no sense to me.
the kids that were watching seemed to enjoy it.
Now i'm a massive fan of stitch and i'm prob one of the only people in the world that actually likes Stitch's Great Escape but this show needs a little bit more put into the story in my opinon and more disney songs. Again i didn't understand why we were hearing "These Boots Are Made For Walking" in the middle of Tomorrowland. But thats my opinon i really want to see something good happen with Stitch in the parks and i can see why people don't like Stitch's Great Escape.
