I think with Buzz, they should have treated it like it was Star Tours with that level of detail. It would be so awesome if we actually felt like we were going to partake in a real space adventure. Kids woulds love it, grown ups would love it.
I think where the really blew it is using the Etch-a-Sketch as a screen. It's a fantastic effect but it kinda tells the guest "yah, this isn't real... these are toys". So what that does is not transport you into the real Buzz Lightyear world. It transports you to the Buzz Lightyear living in Andy's Room world.
It's just another instance of Disney having the power to give us Gold but decided to go with Bronze instead.
