I think the conceit of that ad is a lot of fun.
Can I start?
I think replacing the first lagoon scene - an expansive "natural" environment - with a narrow, enclosed tunnel with (presumably) nothing physical to look at certainly diminishes my interest in seeing this revamp come to Orlando.
The grand "Welcome to Jurassic Park/World" moment with the gates swinging open is likely gone, too, or else it's taking place in/leading to a dark corridor, which probably won't have the same impact.
I guess we'll have to see. The ride has already lost a good handful of AAs in favor of CGI stuff, though.
The idea - in concept - could be fun, but:
1. The CGI looks pretty cartoonish (as the Mosasaur does in the movies, frankly).
2. It's coming at the expense of "real," physically-in-the-same-space-with-you stuff.
