While not great, it was indeed nice. I guess I'm a bit turned off because it's weird to see that version of Robotnik like that. The AOSTH version was far goofier. I guess this was at least an attempt to do something different. Some of it is a bit ugly. That was most likely the point.
It's great to see his face so distorted. It's just laughing in this ridiculous manner. I like the background too. You get the sense of being in this bizarre world. It is unique for this version.
