Though ofcourse theres going to be a big gap in anime animation between decades so lets list only the animes made after 2001. List the anime and the year and reason why you thought it was poorly done. Suzuka (2005) is taking the cake for me. The drawings are inconsistent. The proportions seem off and the detail on the characters range from good to half-assed. The close-ups are well drawn but full body shots are often less detailed or out of proportion... This is the only one I can think of right now. Im watching the series right not and this came to mind as probably one of the poorest animated recent series Ive ever seen.
