total bullshit
im not offended by anything to do with columbine at all AND i would be able to see the humor in making fun of it, if it was done right, but this is just trash, poorly optimized, huge file yet terrible audio and image quality, virtually no animation to speak of. its not that it's offensive content, really, its just that its completely unfunny. and no i dont mean that as in, 'it wasnt funny because it was offensive', in fact its barely even offensive because you cant tell what the hell is supposed to be going on.
Maybe its funny to you to spam newgrounds with this crap so people will waste time watching and reviewing it, but you definitely wasted more time creating and uploading it.
since you asked us not to rate the animation (which makes no sense beacause this is a flash movie site) and to rate based on the humor instead, i have. 0/5, 0/10.
