Arches is honestly fine. It delivers exactly what it promises: there are arches. You definitely get what you seek, you and the thousands others. Oh you thought it was going to be a magical moment in between alien-arches? Think again.
The problem is that the entire park feels like a geological scavenger hunt designed for people who don’t actually want to hike but rather take pics. You drive five minutes, park, walk 0.3 miles, look at a rock with a hole in it, take a family photo where at least one child is visibly miserable, then repeat the process for six hours.
Delicate Arch is cool. Landscape Arch is cool. Double Arch is cool. But eventually you realize you are spending your entire day evaluating increasingly minor variations of “rock but curved.” Just go hike nearby.
