If you're going to spend 30 million dollars to bring back the PeopleMover, wouldn't you want to make sure people were going to flock to it? Aren't you going to make sure you can actually make back your 30 million dollars?
That's why they need to either theme it to a movie or make it a thrill ride. The old Peoplemover has almost zero marketability.
Peoplemover will either come back as a 4 minute thrill ride, or possibly as a dark ride with the track length shortened.
