I kind of lose people when they equate high wait times to popularity. Some things are very slow loading and therefore tend to have very high waits (Frozen Ever After, Peter Pan). Conversely, fast loading attractions can seem less popular since you tend to fly through the queue (say, Pirates). I would not say Pirates is any less popular than Peter Pan in a total popularity standpoint, yet judging by wait times, Peter Pan would be considered far, far more popular in most cases. That's why I find that logic flawed.
On the topic of Dinosaur, if you want to do the wait time argument, it typically is 30 minutes or so midday and stretches to 60+ on busy days. Is it the most popular in the park, no. But is it ridiculously unpoular and begging to be replaced? also no.
I hope I'm wrong and I hope the Indy version is great but recent track record has me worried for a cheap overlay.
