I haven't watched any part of any of those series yet.
I am finding so many great anime series that are not vastly long and take up vast amounts of storage space that I don't feel the need to set aside bandwidth and time to download and watch them. My ISP package includes a file transfer cap, so I've got to manage my bandwidth usage carefully. Also, I tend to follow Starl1te's notions.
Maybe some day I might check those series out, but it'll most likely be by borrowing the first few episodes from a public library or maybe a cheap purchase from a department stores DVD bargain bin. I've no compelling need or desire, though. It's not that I have a dislike for them, but that I haven't any strong desire to watch them.
Gems like Kenran Butoh Sai, Kemonozume, Everyday is Sunday, Kaiba, Oruchuban Ebichu, PlanetES, Elf Princess Rane, Sadamitsu the Destroyer, Starship Operators, Haibane Renmei and many, many others, are far more attractive to me, so they tend to absorb my viewing time.
