My thought process: Ooh, dead people on the moon! Giant robots! This could be pretty cool!
Ten seconds later, a gusts of wind blows up the skirts of a gaggle of girls: Never mind.
The sad thing is, I thought the setting had a lot of potential. It reminds me a lot of Gunparade March, in that a group of students fights a losing war against invading monsters.
For some reason I tend to really enjoy stories that focus on the losing side of a war, such as Gunparade March and Simoun, my all-time favorite anime. Indeed, the end of the first episode of Muv-Luv began to improve as it shifted focus from the changing room to the battlefield, where the humans begin to die and to wallow in despair.
Unfortunately, the setting is not enough to make up for the facts that this is largely an excuse for bad fanservice and that none of the characters interest me in the slightest.
