Zankyou no Terror (Terror in Resonance): *sigh* This anime... I honestly don't know how to feel towards it. Here's the thing. When you listen to a classic piece of music, let's say Mozart or Beethoven, you know that it is a critically an acclaimed work, many people nowadays will nonetheless be bored by it. Some people though will appreciate what they are listening to and give the piece of music the credit they deserve.
In a way, that's how I view Zankyou no Terror: I'm aware of the the fact that it is a good anime, but I'd by lying if I said that I'd completely enjoyed it. And the ending... It wasn't bad, but I hate these types of endings nonetheless. It's hard to swallow such endings.
The main reason I started this anime was b/c I've found out that the director of this anime also directed Cowboy Bebop.
I was disappointed with that ending too. I enjoyed it quite a bit up until the end, and came away from it thinking, "That's it?". It left me feeling kind of hollow and unfulfilled.
