FilmAffinity
FilmAffinity is a movie recommendations website created in 2002 in Madrid, Spain by the film critic Pablo Kurt Verdú Schumann and the programmer Daniel Nicolás. Also existing in an English version, the site is very popular in the Spanish-speaking countries, and it was chosen by PC Magazine one of the best entertainment sites of 2004.
Registered users can rate movies, find recommended films based on their personal ratings, create any kind of movie lists and—in the Spanish version—write reviews.
