According to the BBC:
The game's played by two teams of two, everyone involved is active on the comedy circuit.
Rounds are: "What did I buy?" - after hearing some real reviews, try and guess the product being described.
"The reviewee bites back" asks the panel to imagine how a business owner might respond to some complaints on social media - and then Frank reads out the original response, which is often funnier than the comedians' efforts.
"Where on Earth are we?" gives real reviews of tourist attractions, and asks the panel to deduce their location. Scores are totted up, a winner is declared.
One Person Found This Helpful doesn't really know if it's a quiz with proper answers, or if it's an improvisation comedy show. The programme seems to want to ridicule the cult of online reviews, but is too darned nice to follow through with it. The result is a laboured programme, and not a particularly funny one.
It didn't help that One Person Found This Helpful was commissioned straight into the Monday 6.30 comedy spot, where we'd normally find Just a Minute and I'm Sorry I Haven't a Clue and The Unbelievable Truth. Perhaps a lower-profile slot would have been helpful, while they perfect the format.
Devised by Jason Hazeley and Simon Evans with the producer David Tyler.
