Jeez.
Why does everyone forget that lightsabers are pure light? They are so hot they would not leave blood. Did you see any blood in the Star War movies? No? That's because they didn't run out of red paint. It's simple logic. Something that hot would instantly fuse the veins, arteries and capilaries back up. After seeing Killbunny 3 i thought this aswell but i just really had to get this rant out.
Peace.
Oh yeah, the mouth didn't ever change that kinda annoyed me.
