I was surprised to learn that this was the same guy who did Hwangsanbeol and Pyongyangseong.
I think those films are meant to be parodies of the historicals
These two are definitely parodies, yes.
Although they are supposed to be parodies and should not be taken seriously, I have to point out one flaw from the movies.
I'm sure nobody spoke in any modern Korean regional dialects back then, but Baekje people speaking in Jeolla Dialect is wrong.
Baekje's capital cities were today's Seoul for 500 years and 200 years in today's Chungcheong region. The royals and main nobles of Baekje never had anything to do with today's Jeolla region. Making them speak in Chungcheong dialect would have been more accurate, not Jeolla.
The director probably wanted to reflect the modern rivarly between Jeolla and Gyeongsang region in a historical, but this gave the wrong impression to many Koreans who aren't familiar with ancient history. Many people who aren't really interested in history thought Baekje's capital and main areas were in Jeolla province because of this movie.
