Shrek is one of my favorite animated movies today, despite my age I still like it and as you say there have been several productions derived from this great movie, how is the Puss in Boots which is another one I want to see but I have not yet done so.
The truth is that I knew a lot about the animation of how this movie was created, I am not very critical of this since I am not an expert at all but thanks to this review I understand a little more.
Greetings!
