Does anyone here use this site? Since I started using it a month ago it has been indispensable to me. It's extremely useful for keeping a record of all the movies you see and when you see them, as long as you're inclined to rating them as well. I'll give a basic rundown of how it works.
If you are new to the site you can import all your imdb rankings so that you wont have to rank all your movies again.
Next, there's the Taste Compatibility Index (TCI). TCI is a rating that you have with every other user, comparing your tastes. The most useful aspect of this is that on individual movie pages, you can sort ratings by your closest TCI.
Perhaps the most useful tool of Criticker though is the Probable Score Indicator (PSI). This generates the likely score you will give to any unseen movie, based on all the ratings of the users with the closest TCI.
The film database features are also very intuitive and useful. There are a bunch of genres to filter by, all based on the IMDb genres of a film. You can filter by any year-to-year range you wish, the films popularity on Criticker, or any individual filmmaker. There is also the ability to sort whatever you filter by # of rankings, year in ascending or descending order and most importantly, PSI.
The community is filled with well-watched cinephiles. I'm posting this here to hopefully bring some more in. Whenever you rate a movie you have the option of writing a 500 character max. mini-review. There is a very estimable set of users that regularly post these.
There are a few other things you can find out for yourself about the site, if you like. I hope this brings in some more users, as I think this is an extremely under-utilized website in general.
