The show did reveal that Commodus was cheating by having the swords of his opponents dulled and made weak so they would break. It was covered in a lot of detail.
It characterized Commodus as a blood thirsty, crazed lunatic.
It showed him to be a lazy, no-account, shiftless, lay-about from an early age. Marcus Aurelius tried to turn him into a man in the wars in Germanic, but by then it was too late.
I may be confusing it with another series. My apologies.
I went back and watched Episode 6 of Season 1. I stand corrected. They did indeed show that he had rigged his battles. But they didn’t show the extent of how bad it was and that he fought cripples and amputees. Much worse and sickening based on contemporary accounts.
He did have great hunting skills based on the same accounts.
