Tennis legend Serena Williams shares a personal account of her career milestones Certificate: pg 'It's lonely at the top... at the end of the day I wasn't there to make friends, I was there to win,' Serena Williams says, narrating her own story in this exhaustive, but far from exhausting, eight-part series. It certainly wasn't always about winning for Serena as she explains how it felt, as a youngster, being in the shadow of her sister Venus, not with any bitterness, but with love and a smile. As part of a poor black family growing up in the LA neighbourhood of Compton, the Williams sisters were always going to stand out the minute they started playing pro tennis in the 1990s, spurred on by their dad Richard, who referred to Serena back then as a 'pitbull'. Both Serena and Venus are winners, but are also charming and self-effacing, especially as they reminisce about their early career, with Venus describing her sister's pro-debut as 'so cute'... and Serena laughing off how bad it was. It's definitely a bit of a puff piece, but even carefully managed and presented, Serena's story is still a belter and as thrilling as her exhilarating on court style. (Eight episodes)
