A beautifully told story of the battle between men and nature. I would highly recommended Princess Mononoke for just about anyone, really.
In doing my best not to write any spoilers, I'll keep this as helpful but brief as possible. I think the art and animation are wonderful; any fan of animated movies would appreciate Miyazaki Hayao's work. The protagonist is your regular hero: a character with a strong sense of liberty and justice (it'd be hard to find a Studio Ghibli protagonist who is not as such). I found the pacing and storytelling well done; there were no scenes that dragged on nor any that were vague and unneeded. Lastly, this movie delivers an important, often forgotten message to our generation and those generations to come that we should hang on to.
Overall, I highly enjoyed this wonderful movie and hope that others will as well.
