I absolutely agree with you, jt. People don't remember (or realize) that the ticketing system was there in part to encourage traffic to the less-popular attractions and to capitalize on the popularity of the more in-demand attractions.
Heck, half of the Magic Kingdom E-ticket attractions are hardly what I'd call epic in scope or heavy on the thrills (two criteria many on this board and the modern theme park community use to define E ticket attractions), but all were popular w/ guests in the early years of the park: Space Mountain, Pirates of the Caribbean, Haunted Mansion, Country Bear Jamboree, Hall of Presidents, Jungle Cruise, It’s a Small World, and 20,000 Leagues under the Sea.
Objectively, I believe there is enough in this attraction that would satisfy both the original and modern definition of an E-ticket, and it's going to be immensely popular for quite sometime. Anyone that thinks otherwise is allowing their bias against Disney/for Universal to color their judgement.
