the main story is very good. i will admit it takes a while to get going but every anime needs to take time to introduce the ideas, however this series takes about 5 episodes just introducing the ideas, a little long by my standards.
after the introductions the story plays out rather well, lots of action and fighting with giant robots yay. and as the episodes progress you will find your self at the edge of your seat. events occur that make you want to applause others make you want to kill who ever it is that speak. it can grab the mind and soul of any true anime fan.
however the ending is a little sucky and slightly confusing. after seeing many anime you have a certain expectation for how it should end however this series leaves you with a fair few questions. over all the very last two episodes are rather confusing, they have some relation to whats happened in the story but the ideas used arnt exactly wrapping up material.
in short a good anime but bad begging and end only 7/10 kudos
