Yep, and IMO it's lightyears better than and more re-rideable than FJGringotts also got blasted by fandom when it opened. The GP rightfully loves it though. Generally, short of Hagrids, it has the longest daily lines at Universal, even though it's a pretty high capacity attraction.
I think everyone built Gringotts up in their head a bit too much
Same with Mummy really, part of that was Universal's fault
But yeah, the GP doesn't normally have any pre-concieved expectations
