if l liked an anime l buy it, supporting makers is important, otherwise they make shit next time, or half the episode they do is dialog pictures and red/black screens of doom, with the biggest ammount of important stuff missing evah.
well, l buy what l like and what l can to support those ppl that su[pport us with entertainment.
you should do the same.
as for BDs, well, thats a give, BDs are gonna kick DVDs in the balls and cripple them a bit, but definitly not gonna kill it, even now there are cd's .
l say, buy what you liked, it's worth.
