Revealing mistake: When Nova blasts through the building, the wall where the hole is created has already been drawn as misshapen and discolored, likely to make it easier for the animators to animate. (00:02:53)
Continuity mistake: When Frankie is telling Johnny that she has been reading about him, there are several men in the background. A couple of shots later, the characters in the background are different people altogether, including two women. (00:01:07)
Continuity mistake: When Frankie and Johnny are kissing, just before Terrax arrives, they are next to the spire of the Empire State Building. When the shot changes, they are suddenly in outer space. (00:05:53)
Answer: Gleaned from the Internet: Much of the negative reaction was due to the poor, simplistic, and outdated quality of the animation where the characters moved stiffly and clumsily through scenes. There were also some obvious animation compositing gaffs. The animation colors were also criticized as being overly bright and cheery and out of character to the established story's darker tone. The broad humor of the first season was replaced by a more mature narrative between the characters.
