Nintendo has a "kiddy" image because by and large they are more kid-centric than the other two console makers who market primarily to teenagers/adult males first and foremost.
Also most Nintendo franchises that end up defining the platform are cartoony/Disney-esque in nature.
A Ninja Gaiden port with more blood is not going to change that really. It doesn't hurt though.
