I agree, but the 2005 Peter Jackson KING KONG movie is just one of many retellings of this character and I'm sure there will be many more in the future. I don't think the attraction will follow the 2005 movie to a T.
The great thing about KONG is that you don't need to have seen any movie. All you gotta know is that it's a big gorilla and you're sure to have a great time on the ride.
