Tough, Intense, Insightful and Discussion required with a mature tween or a teen.
Visually a stunning movie with a very well developed viewpoint against the use of science as a war mongering tool by anyone. The movie has many intense moments and conflicts between the two father and son relationships culminating with one father attempting to kill his son. Not sure how it differs from the Star Wars Trilogy with Darth Vader attempting to kill his son over the length of 3 movies.
Personally it created a great amount of dialog about father/son conflicts and human morals between myself and my 10 year old son.
I found it more positive and overall less disturbing of a movie for a tween than most of the Star Wars movies and the Tolkien Trilogy. However, it did require a bit of explaining and discussion, which is also good.
