I was actually a bit unimpressed? Which is a shame, because I had been waiting for this since it was announced.
Complaints aside, I did enjoy this, and the more I reflect on it, I think I was just caught off guard by the slight character changes and the uber crisp animation. With another watch, I could see myself appreciating it, but I think the majority of my complaints just come down to Jhonen being a bit rusty and less familiar with his original character concepts. If there's any sort of continuation, I'm still in.
Really, though, I'm hoping that the Squee! short film that he talked about however many years back comes to fruition. I'd love to see what he could do when he doesn't have to cater to children.
