True, but I understand BehindTheTheme's concerns. I don't think money will necessarily equal success when it comes to theme park shows. Just look at Creature. Very high production values, but almost universally panned by fans. WaterWorld - in all honestly - was a fluke, in that it just works. Plus, they've had the advantage of honing the performance into a well oiled machine for the past decade or so.
Personally speaking, I think many theme park stunt shows suffer from periods of dead space. WaterWorld succeeds because it's constant action happening all around you. There's never an awkward transition period, and the entire show is just seamless.
That's my concern. Whether or not this formula can work with another franchise.
