The Mask of Doom: Part 3 - S1-E10
Factual error: When the Persians launch the boulder at the Greek ship, it falls short and lands in the ocean. The ensuing splash is far too small for the mass of the boulder and the velocity at which it landed in the water. (00:15:31)
Answer: Gleaned from the Internet: Much of the negative reaction was due to the poor, simplistic, and outdated quality of the animation where the characters moved stiffly and clumsily through scenes.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.
