Troubled Production: Aside from the unexpected decision to extend the show to 39 episodes (hence the Korean-animated filler arc), there were other problems plaguing the show's production progress. Anno reportedly disliked the original script for the show, and decided to rewrite it from scratch. Furthermore, any "suggestions" from NHK on how to "improve" the show were instantly disregarded, hence the Darker and Edgier tone for most of the canonical episodes. Because of Anno's demand for perfectionism, many episodes ran late, with Anno spending more than eighteen hours per day on the show! At one point, after episode 20 was broadcast, it took an entire month for audiences to see the subsequent one. The budget for the show also caused Gainax to lose more than ¥800 million (half a million dollars!) in finances. They were also denied any of the rights. Perhaps because of this, neither Gainax nor NHK worked together on another show, while Anno fell into the heavy bout of depression that led to Neon Genesis Evangelion.
