I call bullshit on this argument.
Knox isn't here to impress any of you. He started claymation as a simple passtime (or so I gather) using little blue claymen. Over time these figures became his trademark and so he sticks to them. They're easy, quick and effective. Anyone who actually sits down and watches a Knox claymation would know that his movies are focused much more on humor and the seemingly pointless conversations his characters engage in, rather than the claymation itself. Not your kind of humor? That's fine - just don't bitch about it.
You don't have to like them. You don't have to watch them. It's as simple as that.
How exactly is Knox whoring out his own fanbase here or bastardising Newgrounds claymation? He makes claymations because he enjoys doing so - you think he has control over what others will think of them or whether they'll make it to the frontpage? Of course not. People like his work, and hence he became a success.
There's no need for personal attacks toward Knox for doing what he feels to be constructive and/or creative. File your complaints elsewhere.
If you ask me, NG users just think it's cool to hate popular artists for the sole reason that they're popular. Get over it.
