Terra (2007)

Also known as Battle For Terra, this animated film mixes soft, digital animation, solid voice acting, and an overt political warning about the danger of military invasion. Its hard not to compare it to Avatar, as I just saw it, and certainly some parallels can be made between the two. While its no grandiose technical achievement, or monumental masterpiece, as many are considering Avatar, I do think that it is arguably its equal (or perhaps better) in regards to heart and message. If you can look past the animation, which some may label as too child-like, there's a riveting story that dabbles in very adult themes (death, betrayal, sacrifice, etc.).
