For the most part, I enjoyed this show. Nice story concept, good characters and development of them, etc. The part that takes this show from an eight to a seven is the ending and the unexplained from the abrupt end. I am still confused at what happened and astonished at how fast they tried to resolve the entire plot in about 23 mins when it should have taken at least three times that. Due to this, there is still a lot of things that are unexplained, such as the infertile alien egg and the whole valkyria sister thing. I am still giving this show anabove-average score because this show is worth watching. Now it doesn't resolve cleanly, but I still recommend 11 of the 13.
