In Episode 3 (Insane to the game). Conor McGregor is in his hotel room weighing himself on a scale- he is visibly nude but nothing explicit is shown.
A ring girl wear very minimal clothing as she displays the ring card for the fights.
Violence & Gore
Severe
A lot of blood can be seen in the series from Conor and Conor's opponents but the camera doesn't linger on the blood.
Conor breaks/dislocated his toe in the first episode of the series- it's uncomfortable to watch especially with Conor grimacing in pain.
Profanity
Severe
A lot of f-bombs and frequent uses of shit and damn are used by Conor, but nothing offensive towards certain viewers (not appropriate for younger viewers).
Alcohol, Drugs & Smoking
Moderate
Conor in a two episodes promotes his drink Proper Twelve which is an Irish Whiskey, he doesn't do it in a harmful way or inappropriate manner- he takes one shot of the drink in front of a crowd- but nothing major.
Frightening & Intense Scenes
Mild
A lot of fighting can be seen which is understandable for a documentary focused on one of the biggest names in UFC history- all episodes include some aspect of fighting- may be frightening for some younger viewers but nothing that can scare any mature audiences.
