Mr Pink's is a standard review site with a good range of reviews, divided into the usual categories we'd expect to see.
Choose your favourite porn category and away you go with a list of all available reviews. Some categories (such as Foot/Leg Fetish) have relatively few reviews. In some cases a site is summarised in a single paragraph together with the price of membership and a link to the site. For some this may be enough but if you are looking for an extensive review you may not always get it here.
On the plus side some categories (such as Amateurs) have quite an impressive list of reviews which are a lot more thorough and you get a very good feel what what you will get for your money in these cases. The rating system is a straightforward 1-5 stars but is only used for the longer reviews and is not broken down by particular features of the site (such as content, layout, update frequency etc).
Mr Pink's doesn't have the biggest number of reviews or the most extensive but is definitely worth a visit as it may just have the review you were looking for. They also have some special offers if you choose to sign up from their site and in some cases you can get half price memberships.
In summary Mr Pink's gives you a pretty good range of straightforward reviews with some good deals on membership. It's definitely worth a visit but might not always be your first port of call.
