Good, but not that good.
In my opinion, it didn't need to have *that* much gore. You could've made it slightly less realistic. As it was, the gore was somewhat distracting from everything else. Hence, the 6 in style.
Secondly, the lack of any character development or humor was bad, although I realize that it may be better in the full thing. There were a few hitches in the animation, such as a bullet staying still for several frames, but it was overall pretty good. The drawings, shading, etc, were all excellent. And the sound matched up well. But all-in-all, while the artwork is excellent, I come to Newgrounds to be entertained, and it wasn't really entertaining. (Although the car-alarm-lock-sound right before the bomb part was funny enough to earn a three.)
p.s. The one for interactivity is my default for N/A -- to get a zero would be the sort of thing where you have to click "next" every two seconds. Just so you know.
