The film also stays emotionally grounded in the relationships between Thelma and her family, giving the characters enough space to like and care for each other.

What unfolds is Mission: Impossible on Mobility Scooters, with a soundtrack to match. Thelma and Ben after the crooks; Danny and his parents chasing Thelma and Ben. It is full of humour, and not a little sadness.

The key to all this is Squibb’s success in convincing you of the close contact Thelma maintains with her younger self. You can see the girl in her.

It’s rare to find a movie that balances sincerity and silliness so effortlessly that it blocks out any sense of modern cynicism.
