I have a simple rule for anything that is shown on a comedy channel.
It should be funny or else it is a breach of the trade description.
Billed as being from the makers of Fleabag. Creator Vicky Jones was the script editor for Fleabag. I take this to mean she did not write the jokes.
The first episode is a woman who receives a text with the word 'run.'
She leaves her life behind which includes husband and kids and meets up with an old flame on a train.
It seems Ruby and Billy once made a pact about getting away from their lives if it got too boring.
On the train they talk, flirt, bicker and play pranks on each other. Whatever it is, it did not pass for humour.
