The British hospitality industry is under attack. Businesses are being assaulted by ever-more nit-picking and abusive reviews. It's bad for their livelihoods and their sanity.
But it's not the professional critics who are reviewing their hosts; a nation of virtual AA Gills and Michael Winners are using the Trip Advisor website to get their own back on hotels and restaurants.
With more than 40 million users a month, Trip Advisor is the largest and most powerful travel guide in the world.
But is it a force for good that gives the customer a voice, or an abuse of power that undermines businesses and ruins lives?
How long can Britain's small businesses cope with relentless criticism before they pack it all in?
This Cutting Edge film reveals Britain's most meticulous Trip Advisors and meets some of the hoteliers and restaurateurs at war with the site.
