It's hardly a wild proposition. Walt Disney Parks and Resorts is under extreme pressure to reduce costs. A broken, delayed, over budget show is a perfect poster child for what Chapek is trying to 'fix' within Disney's design culture. If a clip show can hit the right guest satisfaction marks (which it will if so desired), then what point is there to continuing to pour money into a non-"Disney" show? The only saving grace would be if Cameron was really into the show, which does seem like a strong possibility since the show even made it off the drawing boards.
