I choose an option not on the list. At some indeterminate point in the future, if it gets a DVD release I may be morbidly curious enough to put the first disc in my rental queue as a low priority item, so would see it at some indeterminate point after that.
I'll download, I learnt my lesson with Animated, the UK screening was horrid how many times did they suddenly jump back to the first episodes before eventually getting to the end. And the lack of DVD shows you can't rely on that. Somewhere along the the line I started watching on youtube rather than downloading so I'm not sure if I have a full set or not now.
Prime doesn't really look that impressive from the little I saw, but people said the same about animateds early previews so I'll give this a chance.
