"This directly affects the animation quality" The character designer of OPM anime Chikashi Kubota literally debunked this popular misconception. A long time ago he said in an interview that S1 had an average budget like MOST anime, the quality was the result of the talented staff, good management and schedule. Good animation is never determined by the budget. This video is sadly filled with misinformation.
Yeah, the manga art is great, but the series overall is boring. Saitama is the only interesting thing about it, and that was completely exhausted in the first art. The rest is all shounen BS.
