If you buy a rubbish computer game, you can slate it online.
If you book into what promises to be a five star hotel and it's more like a damp hole in the ground, you can log onto a review site and warn people off it.
Similarly, if you got amazingly good service, you might want to rave about it on message boards.
The same idea is behind a new website I Want Great Care.org which allows patients to rate the UK's 40,000 GPs and 120,000 hospital doctors.

"None of us would buy a book or a bike without seeing what other people think. Yet something really really important like our health, there isn't any such service," said Neil Bacon, who is the man behind the idea.
"So if it's important to read what people think about simple things, how much more important is it for something as important as your health?" he added.
But he says some doctors are so angry about the site they're trying to sabotage it by putting up fake reviews.
"They've tried adding spoof reviews about some of the famous doctors in the country saying 'We don't like this person, they're not very good'. It's clearly rubbish."
Open to abuse
Patients can log onto the site and give their doctor a percentage mark from 0% to 100% on The Big Three Questions: Do you trust your Doctor? Did they listen to you? Would you recommend them?
Kaine has reviewed his doctor on the site and he said he thinks it is a good idea.
"It'll keep doctors on their toes. I'd recommend the site to people who think the doctor's good or bad because it helps other patients decide whether they're performing as they should be."
But Dr Richard Vautrey from the British Medical Association, which represents doctors disagrees.
"We have concerns this website is open to manipulation. It would be possible for family friends and colleagues to go onto this site and hype up a particular doctor.
"Equally, it would be possible for a patients with an axe to grind to highlight that a particular doctor is particularly bad when that's not the case," he said.
The people behind the website though, who are doctors themselves, say the site is regularly monitored and security checks stop that from happening.
