ugh. decent.
Occasionally it was good, but mostly it was pretty crappy, especially with the use of red shading all over the place. Call it "artistic style" all you want, but really it's just MSPaint-esque. Coulda been done way better. There's more than just 6 shades of red, you know.
It's pretty choppy, even when you tween. Please make use of more frames per second. Also, those brush mouse drawing are pretty bad (usually) but there's a couple of good ones.
The whole movie moves very slow, even if that's intentional. And repetitive. Have a little more faith in your viewers to understand the message you're trying to put across and keep it moving along.
Hey, I guessed it was Metallica, and got it right. Hope this review helps.
