Angst must be some sort of buzzword lately for I can't go a day without someone referring to it in one way or another. Dictionary defines it as a feeling of anxiety, apprehension, or insecurity. That's pretty broad... by that definition I think that probably every anime has a LARGE AMOUNT OF ANGST. Hell, any DRAMA for that matter. Any human being? You be the judge of that. But like I said; angst has buzzword written all over it, so while it may apply to Evangelion or Gundam, it also applies to pretty much everything else.
Depth also seems to be dominating conversations about everything from web comics to feature length, episodic films. Does the depth or perceived depth of something really make it better? 2001 is supposed to be pretty deep and while I understand it, I find it as boring as watching paint dry.
I love Evangelion, but the deepest aspect of the show culminates in the final 2 episodes... you know.. the ones that everyone hates? I think that a lot of people mistake a convoluted story and red herring references for this 'depth.'
