I have yet to see something more than an advertisement for some school, so it really doesn't affect me in any way... Although, I can see how it would appear to someone that hasn't had very little to no experience in martial arts. Some cartoons can be seen in a negative way to certain people- instead of drawing more practitioners, it could dissuade them. Just a thought. Some could, for example, think that martial artists are not very good, and wonder "why bother?"
