Just finished Planetes and it was fantastic. I gave it a 9.1 which is #4/14 of my anime ranking list. It would have been ranked even higher if it wasn't for the fact that the ending wasn't as good as I think it could have been, but the ending was still good. It's just that (spoilers ahead)
Spoiler:

I was kind of disappointed that Hachimaki still went on the Van Braum. I really expected him to give up his spot in the crew so he could stay with Tanabe, and I'm disappointed he didn't.

Side note, I totally called Hakim being in the Space Defense Front the first shot I saw with him holding a briefcase. I want to know when Claire joined though. She wasn't in it all along was she?
