Blue Planet III has made its long-awaited return, with David Attenborough once again providing the familiar narration
After four years of filming, the opening episode explored tropical seas, combining striking underwater footage with a warning about rising temperatures and the damage they can cause to coral reefs
Viewers described the programme as deeply moving and visually magnificent, despite its sombre moments, while praising the series for making ocean conservation feel urgent
The latest instalment follows Blue Planet II, which aired in 2017, and arrives during Attenborough’s 100th birthday year.
