I already had that with episode 13!
I bought series one on its own and when I got to the last episode I said "aww shit, shits getting real now, three robots and tomatoes!"
Then it ended and I ordered Series 2 for transatlantic shipping the next moment.
Episode 14 was quite weak though, and series two took a while to get good again.
But, my god, is it good.
DEAR JAPAN: STOP MAKING BULLSHIT LIKE KANON AND KANOKON AND MOE CRAP AND MAKE BIG O SERIES 3.
