Not bad. Overdone though. Hell I've helped make two of them myself as you know and I've seen about 5 or so of these done on newgrounds.
Animation/Graphics - The text was easy to read and the colors were user friendly. I think that you hit everything here pretty well. The only thing that I can think about is a couple of times I saw typos or places where the words and text didn't line up the best.
Story - The information itself was pretty good, but you really didn't cover everything. You want to try and cover everything when making a flash about abusive reviews because leaving just one thing out could make people lose their whistle status or miss out on some things.
Audio - The audio was a nice selection. I was hoping for maybe a menu with a couple of selections to choose from though. And maybe a mute button. If there was one sorry, but I didn't notice it.
Overall, the more of these out there the better in my opinion because the more people will learn.
* Side note - Do people find this review as helpful, useless, or abusive?
