Comic Book Confidential

I felt the movie "Comic Book Confidential," directed by Ron Mann illustrated the history of comics, and comic book making very well. Approaching each, and every artist, creator, or well known figure related to comics. The very first comics began in 1934, sticking strong till 2011. However the only flaw I seemed to notice throughout the film, is Ron Mann never approached the topic of comics relating to well known novels. There were huge comics relating to Huckleberry Fin, The Odyssey, and Tom Sawyer throughout the later 1930's-1950's. Some comics were even combined stories, such as Huckleberry Fin, and Tom Sawyer. I would've appreciated this film much more if they had gone more into detail about the comics, and less about the creators. The only comics they approached were the well known Superman, and Batman comics (yes very major comics) however hearing more of the unknown comics would have been a little more appealing to me.
