Too many people bash on open endings. I wonder if that's the case. I believe in the artists' prerogative when it comes to these matters. If an anime creator sees fit to leave me hanging at the end of their anime, with no resolution; I simply ponder my own conclusion. This is much akin to finishing a good book. "Wow! I can't believe that! That really happened? Oh man, I wonder what happened to... blah, blah, blah." Know what I mean? Sorry, rambling again.
No matter where you go, there you are.
