There as some good episode in this group of 12. It has a lot of filler episodes that just boring to watch. The last 3 epsoide were really good. It like reward for sticking through all boring ones. The last three made me want a season 2 This series is about robot girl who lost her memories. It is discovered that they help with driving the mech and have powers. It take place post apocalyptic world. I mean post because a lot human civilization has rebuilt. That why filler episode are boring because you feel there is no danger. They do develop the characters. I only started to care at the end. The pacing could better than all over the place. The 2nd is faster pace and pulls on your heart strings. On some episodes I just want watch next one to see what happens.
