IT WAS the little insights that made last night's 70-minute window into Ronan O'Gara's life so compelling.
Whether it was the darkness that came over his face when he recalled sitting in his father's car and realising a D2 in English had cost him a place on the commerce course at UCC or the raw emotion with which he discussed being the only player to be dropped from the Ireland team after a particularly bad outing against France in 2010, pride, honesty and self-belief shone through.
His relationships with Johnny Sexton and Declan Kidney were key themes, but what ran deeper was the addiction to not letting down his team, the need to win and the rush of being the best that drove O'Gara to such success.
To watch O'Gara and his long-term colleague Donncha O'Callaghan in the aftermath of the 2011 World Cup pool win over Italy was revelatory, as they compared the emotion of succeeding in New Zealand with the disappointment of exiting at the pool stages four years earlier in France.
"Remember this time four years ago?" O'Callaghan asks.
"I'll never forget it," O'Gara replies. "The highs don't ever match the lows, that's the whole thing -- avoiding lows."
Concentrating on the last four years of Ireland's most capped player, Dave Berry's documentary focused on a period in the life of the Corkman when he raged against the dying of the light for province and country.
The end looms large over every moment, whether it's Munster's 2011 defeat to Toulon that saw them exit the Heineken Cup at the pool stage for the first time in over a decade or the win over Australia at the World Cup later that year.
On both occasions, he considered walking away but the buzz of winning and the camaraderie of the dressing room pulled him back in, time and time again.
When the end did arrive, O'Gara (pictured right with his wife Jessica) didn't see it coming. It is perhaps his gut-wrenching recollection of those moments 10 months ago, when his long-time coach Kidney called time on his international career, and his final moments at Murrayfield as everything that could go wrong went wrong, that ring truest.
"It (was) nothing like the way I'd liked it to have finished, but that's sport," he said, as the footage of his miscued kicks flashed in front of him. "That's my last game for Ireland, that's my last contribution, which is staggering really."
With Munster, he was able to say goodbye the right way as he left the field with his son Rua after Munster's heroic defeat to Clermont in Montpellier.
That his storied rivalry with Sexton is now a friendship is emphasised by O'Gara's comment that the Racing Metro and Ireland star's wife Laura "just feels like she's pushed to the side when I'm around. It's just come full circle".
The documentary was a reminder of what rugby is missing without O'Gara the player, but his coaching career is up and running in Paris with Sexton at his side.
No matter what happens, it is bound to be interesting.
