I've yet to ride Fallon but the impression I get is that it has been warmly received. The GP seem to like it and those who thought it would be dreadful were slightly surprised so I'd call that a win win.
This is more SCREENZ, a similar ride to Kong that open only last year (At least Spider-Man and Transformers opened 14 years apart), the CGI looks god awful and it's probably the worst thing they could have created based on the IP.
I don't think this is going to end well for Universal. Luckily, they have a solid line up coming soon that should hopefully distract everybody.
