This hasn't been promoted as an E-Ticket attraction, but rather a solid D-Ticket. I'm looking forward to this ride, and I expect it to be a better attraction than Men in Black, but not as good as Spiderman. It takes elements from both, but it doesn't seem to be taking any of the thrilling elements of Spiderman.
One thing that is being overlooked is the Mr. Potato Head animatronic that will be in the queue. With a completely interactive animatronic having a permanent location, we get to see the next step in the living character initiative.
Personally, I find rides like Men in Black and Buzz Lightyear to be very entertaining. Buzz Lightyear is a definite family favorite, and we often ride multiple times on any given day. I'm looking forward to Toy Story Mania. I don't ask that every ride be thrilling, but I do ask that they be entertaining, and I hope that I have as much fun on Toy Story Mania as I do on Buzz Lightyear or Men in Black.
