I for one say the opposite! I love Dark Knight, it's a great ride that was just marketed the wrong way.
I guess I was just expecting more the first time I rode it (marketing, like you said), especially after the pre-show, which is cool. It's a fun ride, but I've never waited more than 20 minutes for it, and the theming once on the ride is pretty poor. I also get annoyed that so many people get sent into the room for the pre-show and half of them end up getting ahead of me in line when they were behind me because there's no queue in that room so people are standing in a mob. I still wouldn't wait very long in line for it. To each his own. Batman the Ride is the one I love.
