Is it supposed to be a massive surprise that a Universal Monsters land isn't as busy as *checks notes* Harry Potter, How To Train Your Dragon, and Nintendo? Seems like a skill issue in setting expectations appropriately if you went into it expecting Universal Monsters to compete with some of the biggest franchises in the world...
Regardless, like everyone else has already said, that's skipping right past a ton of other notes on capacity currently. Not interested in contributing to the view count for clickbait videos though, so I'll have to take y'all at your word that the argument is that shallow.
