Metacritic

It’s been around for ages but I really love this site. Basically it summarises critical reviews of anything from albums, videos and films to books and TV. I love it. like all the best web apps, it is an aggregator, giving you a quick snapshot of what people are saying. Best of all, the way it is laid out means you can get a good overview in seconds.
They say on the site ‘We feel strongly that multiple opinions are better than one, and also that the presentation of these critical opinions must be done in a concise, organized and easy-to-understand manner in order for them to be useful. We also encourage our users to dig deeper on matters that interest them by providing links to full reviews whenever possible. Finally, we believe firmly in providing a pleasant, popup-free user experience for our visitors. Job done I reckon.
