Sakasama no Patema by Yasuhiro Yoshiura. A girl from an underground world enters a different world which is turned upside down. This different world contains strict rules which she will encounter very soon.
The anime movie was very interesting with beautiful sceneries but it also consists of contrastly elements such as the two different societies. Watching the movie was like a journey full of adventures seen through two different perspectives: an underground girl who did not have any idea of the other world and a young boy who was thaught that sinners had been sucked up into the sky. It is fascinating that these teenagers help each other at first sight even though the other one is inverted and without thinking of any possible threat.
Al in all, the movie contains dramatic parts but it is not very emotional. In fact, it is very enjoyable to watch.
