I love twisted American McGee. Really. But this one just didn't work.
Gameplay-wise, there's only so much "butt stomp it!" one can do before getting bored. A better direction would have been to try to make it a better game, as in completing quests or taking specific actions to actually make the grimm fairy tales more horrific, or even introducing some basic "choose your own adventure" elements and consequences. Unfortunately, polluting the environments to change a stink-o-meter before the goodies clean it up is only mildly challenging to outright annoying.
Graphics are severely lacking, but then again that was the model of the system, so I can't really fault it for that. But playing it on a big screen really does highlight the outdated tech.
My advice is to give it a pass.
