Fuck. So the only character that I like (the last one to be eaten) died, and now I'm left with Yui who is just shit. She kept her cool, but that's about it.

I'm a bit surprised mankind is focusing so much on gundam like machines when there are so many other ways to fight. Not that I know what should be done, but it seems taking years to train pilots for so little efficiency is a tad strange.
Mecha have both ground and ariel ability. When fighting Lasers - stand. When fighting other things - fly. I have no idea why they didn't do the latter more frequently though, since they had the idea right the first time about killing off the Lasers first.

The Beta are kinda stupid too. Just land on top of Kyoto or something. You're aliens from space, aren't you? The only proper explanation for such an advance is if a rare Hivemind/Queen-style alien landed on earth many years ago and has been the sole producer of the Beta forces without reinforcements since.

The suits and mecha remind me of Fafner, while the girls and alien setting reminds me of Freezing.
