Titanic without the iceberg is like Sherlock without Moriarty, or Superman without kryptonite. No conflict, no show.
Hey—its 100 years ago the silly ship sank and took all those lives with her to the bottom—I think the idea is clever and it will make money. Its not like a Holocaust wax museum that depicts the suffering of Jews—and their extermination in Gas Chambers.
The one in Pigeon Forge TN has the iceberg already having hit the ship and water spouting....so far as I know, neither the iceberg nor the ship can move. When they were building it I thought that might have been the plan, but apparently not.
If I spent several million on an attraction and then someone over in China one-upped me, I’d be upset too.
