Both actually. It should be fairly incontrovertible that there has not been any TV anime since the genre's inception that both increased the scope, size, and diversity of their audience while also earning the respect of the broad Western hipster class. And on the other metric, I will merely put forward this challenge:
Can any anime fan here, with a straight face and mind, plausibly nominate a show that they consider to be an absolute equivalent in qualities to a well made American/British cable TV series (ex:Six Feet Under, Game of Thrones, Boarddwalk Empire, Luther, Orphan Black etc.), let alone one that meets or even exceeds certifiable masterpieces like Breaking Bad/Sopranos/The Wire/Deadwood, etc.?
I rest my case.
Game of Thrones isn't even particularly good.
Legend of the Galactic Heroes would be my anime pick.
