So what's the big deal about not depicting Shredder as a normal human?

So I know there tends to be a bit of a controversy when the Shredder is depicted as anything other than a regular human (Utrom Shredder is probably the most known controversy, but see also Undead Shredder and Mechasuit Shredder).

Why though is something I don't really sympathise with. I mean let's face it, the Shredder looks cool but that's really about it, in terms of depth and personality he kind of sucks. He's usually a pretty shallow character, usually driven by revenge or desires of conquest with very few definable traits added. The closest a "normal" version of him has been given something more is the Nickelodeon Shredder, and that version of him just feels confusing to be honest.

You might as well mess around with him, at least that way he'll have something a little more interesting about him.
