Today's top TV tips include documentaries about Martin McGuinness and Greta Thunberg, the return of Operation Transformation and Neven Maguire, and a new US sitcom called Bless This Mess . . .

Pick of the Day

Martin McGuinness, 9.30pm, TG4

Subtitled I Fought, I made Peace, I made Politics, this documentary film assesses the life and legacy of Derry cricket enthusiast, the late Martin McGuinness.

He was a major historical figure in the relationship between Ireland and Britain, and a global figure on the international landscape of conflict resolution as he journeyed from Provisional IRA man to peacemaker.

As Bill Clinton - no slouch when it comes to charm - says in the trailer: "He could talk an owl out of a tree". For those in fear of the Irish language, it’s actually largely in English, but both tongues are given the benefit of subtitles.

Operation Transformation, 9.30pm, RTÉ One

Kathryn Thomas  returns to encourage people to lose weight and get fit with the help of a personal dietician, fitness instructor and psychologist, with webcams monitoring their progress.

This year’s covid-compromised ruin will showcase healthy recipes from chefs around the country who have had to close their doors due to the virus, and Dundalk will be the centre of operations.

Bless This Mess, 9.00pm, FOX

Created by Lake Bell (who also stars) and Elizabeth Meriwether for ABC, this amiable sitcom features Dax Shepard, Bell, JT Neal, Pam Grier, and Ed Begley Jr.

The premise is pretty straightforward: young couple Mike and Rio (Shepard and Bell) leave their home in New York City and move to a farm in Bucksnort, Nebraska, that Mike inherited from his great-aunt.

They find it badly neglected and occupied by a senile old man named Rudy Longfellow (Begley). Deciding to stay, they restore and try to run the farm and find themselves adapting to the strange, tightly-knit community of colourful eccentrics with mixed results.

I Am Greta, 11.15pm, BBC One

The story of teenage climate activist Greta Thunberg is told through compelling, never-before-seen footage in this intimate documentary about a young girl who has become the voice of a generation.

Starting with her one-person school strike for climate justice outside the Swedish Parliament, the film follows Greta - a shy student with Asperger’s - as she rises to prominence, and her galvanising global impact as she sparks school strikes around the world.

The film culminates with her gruelling wind-powered voyage across the Atlantic Ocean to speak at the UN Climate Action Summit in New York City. En route, in an intensely emotional moment, Greta reflects on the enormous toll her mission has exacted.
