I thought it was pretty great. Editing, sound, music, were all on par with what I would consider enjoyable levels of quality. What made the experience sour a bit was the animation. It wasnt the planning behind the animation, because quite honestly, a great many things about it were great ( ex: the scene where the camera flips as she cuts the seekers ). It was more the execution. At many points it seemed movements were forced, resulting in a lack of fluidity, which really is very distracting. Lighting was also a problem, not a big one, but in the scene where the mech ( for lack of a better term ) was in space, highlighted both this issue in particular, and the aforementioned animation one ( in which I also grouped camera animation, as it is still indeed animation ).

Overall though, the episode was pretty solid. The ending did it for me though, music, and the screen shake, and the whole shebang.

Really gives you a sit back in your seat " Woah" kind of feel, one that seems many, including myself, enjoy; don't lose that.
