Right idea, wrong execution.
I fully understand the goals you are trying to accomplish. However, I feel that this is the wrong way to spread your message. You argue that the overwhelming amount of video game Flash, in particular the Brawl Taunts and Awesome series lowers the overall quality of the Portal and makes Newgrounds look shitty by comparison. I would say then, show would NG COULD be. Show what your ideal Newgrounds would be, were it in your command, to argue against the site's increasing change with a really good HIGH QUALITY flash. And I'd definitely avoid personal attacks on the creators, as even people sympathetic to your cause will turn on you if they see you behaving like dicks to people. You obviously have strong opinions about this, and some good artists, and I hope this movie helped you vent, but you need to work to better the community from within instead of ranting on the street like crazy hobos.
