Why wasn't there a National Treasure 3?
Seriously.
Enough BS. These films weren't exactly **** but they were family friendly live-action hits for Disney.
Blaming it on the scripts is ridiculous. As seen on another former IMDB thread.
It's not like they were doing a sequel to "Schindler's List" or "The Godfather". I'm assuming everyone involved in the film knew that already.
This was a very, very successful franchise and then it just suddenly...stopped.
