Just the first five episodes. Kira was so emotionally fickle that I couldn't stand watching him anymore. I've heard he got somewhat better, but I also heard that he slept with Flay, so he can't have got much better and became a masochist to boot. I've seen some of the art though; how exactly does he go from Orb > Earth Alliance > Orb > ZAFT?
Other than that, the others aren't on Netflix or Hulu, I don't want to pay for the DVDs, but I don't want to download licensed works. A friend from college watched Gundam Wing and said it was good, but a lot like 00.
