A swinging boat ride like The Joker Inc. would typically only earn a 1-star rating from me, but due to the themeing, I will give it a one-star boost to two-stars because matching themes across rides is something that I think is key in creating the best experience possible as a park overall.
The Joker Inc. not only does a great job matching the Joker's colors and personality, but it sits right next to The Dark Knight himself with Batman: The Ride just off to one end of the boat.
