While browsing through the movies on Netflix Instant, I came across Origin: Spirits of the Past. As a fan of anime, I decided to give it a try even though I've never heard of it before. Guess it was one of those anime films that failed to make a splash in America.
The film is set in a dystopian world where humans had once genetically altered plants to survive life on the moon. However their experiment is too successful, and the plants become sentient and super-powerful. Because of this the moon is shattered and the Earth's civilizations are almost all destroyed. Now hundreds of years later, the Earth is covered in a dense and super-natural forest with only a small number of remaining civilizations left.
The story escalates when Neutral City resident Agito finds a mysterious girl named Toola locked in a time-preservation chamber. Once she is freed, they discover that she is from the past where the Earth and the Moon were still in-tact. However the industrious army of Ragna wants Toola in their efforts to destroy the mighty forest with a mighty weapon left behind hundreds of years ago for "the people of the past".
