I do think it's a lovely resort but the big error was in the scale of the pool area. It was built on the scale of a Walt Disney World hotel, with some added amenities as there was a common assumption that the majority of guests would be out during the day, exploring the island. Instead, nobody leaves. This is problematic as it means people have to get up at 7am to get a lounge chair or sign up for any number of activities in moderate-to-peak periods. It's not relaxing or good service.It is actually reasonably Hawaiian, so it's not like it's a clone.
I think they did a great job with Aulani, and most people I know who are from Hawaii agree.
Aulani can be critiqued, but I don't think it should be criticized. I'm with @cosmicgirl in saying that it demonstrates Disney's *capability* to commit to and execute a thoughtful, well-themed resort in recent-ish times.
