What Disney must have spent on it, no. But they overspend on everything...
It's a fun, solid ride, and a needed new addition, but it's really Space Mountain 2.0.
Maybe it was just my ride, but I found the projections to be really poor considering the availability of state of the art projection systems and digital animations.
Not to play the companies against each other further, but if Universal had built this you'd hear nothing but complaints it's all screens. Since Disney did it "it's the BEST!". And, not a knock on Universal, this really feels like a Universal ride more than a Disney ride, which I guess was Disney's point in building it since they keep losing market share to Universal because Disney is perceived as "not thrilling/boring" for families with children over the age of 8.
