When the Nemo subs opened, it had HUGE waits the first year 1-2 hours in the beginning. A year later it dropped to around 40 minutes normal. By the third year it gets 20-30 minutes on average and where its been since.
GOTG started out with big waits and it still gets the same waits 3 years on, easily over an hour. On busy days, FPs sell out by early afternoon. And on top of that, the merchandising clearly sells a LOT because any time you go you see people wearing GOGT T-shirts or Baby Groot on their shoulders.
And I was defending it in terms of quality, simply popularity. I was only saying only hardcore theme park geeks thinks that hard about it, hence why I'm here at 9:30 on a Monday discussing it lol. But most of my family and friends are NOT hardcore geeks. They don't spend any time on the internet hashing this stuff out. They love the parks, but they are more the casual fans. They love and hate stuff like everyone else of course, but if it's fun, thrilling, etc, then their sold. I imagine if SM fits those same criteria and since most (not all) love TSM, then they will love it too. Of course we don't know, but if it's literally like TSM, just with webs, I don't know how it won't be a hit?
