'Inspiring' - 'The Notorious' gets thumbs up from Irish viewers
The first of six episodes tracing the Dubliner's return from career-threatening injury to happy-slapping a hapless Brazilian at a comeback bout in the O2 (now 3Arena) and the reaction to the programme was mainly positive online.
We learned he was a dapper dresser, with a penchant for bow-ties (a look echoed by his dad, done up like a waiter at a mid-range restaurant for a barbecue in McGregor's honor).
Fellow UFC star Cathal Pendred tweeted: "The Notorious MMA is now taking over the national broadcaster" and the reaction was largely positive for the first show.
Here is a flavour of the reaction on Twitter tonight.
