I think Japan has had anime so entrenched in its media that its a medium that they can bend to their will, and they will be the only ones who can help push other forms of animation forward. With Disney shutting down their hand drawn animation section that doesn't help but others will have to pass those skills on in some form.
Psycho Pass is a good thing because its the kind of adult anime that many japanese studios have stopped making. We got a lot of it in the 90, but it began to disappear in the 2000's. I think the chief director of Psycho Pass Katsuyuki Motohiro specifically said, that he disliked the safe moe crap that has crept into so much anime, where its more about pandering to otaku than telling a good compelling story. He created Psycho Pass to help break that negative chain from anime and kudos to him for it. There's nothing wrong with a tale with strong adult themes so long as they are handled well. I'd like to see more work like it and do check it out if you can.
It is a shame that western animation usually opts for the comedy route (while some do it well), than any deeper themes or topics. One day someone will break that mold, than just being subtle via kids animation. It'll have to be on Netflix or Kickstarter cause most established studios don't want to know or break that mold.
I think Kickstarter could a positive way forward for all anime after Trigger's success Little Witch Academia. Imagine for a moment anime with a story written by a western writer, but animated by pros from Japan or the U.S. this could be a way to tell better tales, even if they aren't long epics. That would be cool. Wishful thinking, perhaps?
Oh and as for Elfen Lied its not the greatest anime, but some will get a kick out of it. It could have been better without the harem cheese and pointless violence for violence sake. Interesting try, Japan.
Oh yeah, loving Avatar: The Legend of Korra and I plead to all anime fans or not, to watch it. Great animation (sure, not up to animes higher standard but still damn good), characters, world and writing. A shining light for western animated works. The last anime I watched that was as good was probably FMA:Brotherhood. Still vastly enjoyable whether you've seen the original Avatar series or not. (I hadn't, but I will watch it on Netflix). Put any anime biase you might cling to aside and enjoy a great tale.
