It's a toss-up between Stitch's Great Escape and Chester and Hester's. Stitch's Great Escape was a horrible attraction, but it was an attempt at doing something. Granted, trying to make Alien Encounter kid-friendly didn't work 100%, and by doing so they also alienated a few fans, but Chester and Hester's was thrown together for the sole purpose of crowd management, with total disregard for quality. I think I'll go with Chester and Hester's, because it sticks out like a sore thumb in the otherwise well-themed Animal Kingdom.
