How the FUCK does this have such a low score? Either you've got someone seriously hating you, or the majority of voters are really that stupid.
The animation in this was really well done. There was lots of movement and it was really fun to watch. I would suggest using a thinner brush though because the thick outlines are a bit unappealing, but that shouldn't matter when the animation is this good.
The story was also pretty interesting, albeit a bit clche. Voice actors would have really helped this and I'm sure that's why people voted so low. There seems to be some sort of thought that not having voices makes an automatic 0... Also reading text is annoying, especially when there's a lot of action in it.
Another problem is the display. First, you got the letterboxing, which is totally unecessary, and then it doesn't even cover up the entire document, so you can see parts of the stage and the stuff that's on it. If you want it to be widescreen, then use some 16:9 stage size, the max 16:9 size of the Newgrounds player is 910 x512, so you can use that to not have to worry about anything getting messed up. If you want the letterboxing though, then make sure the black boxes actually fit the screen ;)
Seriously though, this was great and I don't understand why its score is so low. It totally deserves at least a 3.5. Good luck on your future animations. I hope to see more from you.
