Katanagatari

at first i dont really pay attention to katanagatari but because i have free time i downloaded katanagatari and it is a lot better than i thought it would be XD since my way of choosing anime is 1st look at the picture and will determine about 50% of my decision after that i will download episode 1 and decide to continue or drop the series XD but sora no woto totally trick me since the picture is really different from the anime

and because of that i still didnt watch sora no woto so if anyone watch it please tell me about the story
btw katanagatari will be airing one episode per month and the total episode is 12 so it will take a whole year until the story complete and every episode is about an hour but what the heck right it just a year kara no kyoukai take longer than that XD
