Well, this is my first review, and I'm not a native english speaker, so sorry for eventual mistakes... I choose to write it in english because I thought the review could reach a higher number of users. I've watched anime a lot, and there are pretty much anime that I really enjoyed, but I never wanted to write a review. Terra e is awesome, in the deepest way of the word. The Story is great, there are few plot holes, the universe created is amazing. I really liked how each character's story was built: all of them were somehow bonded. I love this way of developinga story.
About the art... I was quite surprised! Vivid colors and lighter than I thought when I decided to watch it. The CG is not that good, but Terra e is a 2007 anime, so I can understand.
The characters' developing is fantastic. 10 is not enough to describe it. Childs grow up, adults change as years pass. This show deserves more than 10.
The OST is always exciting, beautiful sometimes and brings some despair other times...
Of course the anime is enjoyable: you will watch all episodes really fast...
Terra e can teach us a lot of things, but the most important one is hope.
