Meh
The "comedic" NG characters (like Tankmen and Bitey) seem out of place in your serious plot. You basically neutered them by removing what makes them special...their comedic value.
And then you went off on this stereotypical "ZOMG! Teh Ultimate Fight scene!" tangent, with two guys flying and warping around while shooting lasers and shit (which is a concept so played out by now that it's tedious and boring to watch) ... I just lost interest.
The Naru-tards and Dragon Ball Z fanboys are going to all vote a conformist 10 on this because it's "serious" and "action-packed", so I figured I'd provide a different perspective.
