Good question. I think people rely too much on wait times as a sole indicator of an attraction's success. Many say if something has a 120 minute wait it's a success, if it has a 10 minute wait it's a failure. There's far more variables then people give. Location, capacity, and operations play a role in wait time too.
Something can have a 120 minute wait. It can indicate it's a very popular attraction, it can also indicate it has very low capacity and can't get riders through, poor operations, or a prominent location
Something can have a 10 minute wait. It can indicate it's a very unpopular attraction, it can also indicate it has a large capacity, good operations, is in a harder to find area, and it's not meant as a E-ticket.
Same way I wouldn't say Pirates or Small World are failures for 20 min waits right now, if this new ride has a low wait that isn't bad. They know when rides are people eaters and when they max out an area's potential, which is why they aren't fighting to remove Nemo or GFT (and Cocopers need to get over it that dream is dead with the DCA build). If this gets more interest and more crowds then now, and of course more merch sales and prominence for the character, it would be successful. Doesn't need GOTG wait times.
