Today I found an amazing web site that lets you choose a name of a movie and all movies that are probably of the same liking appear in its proximity.
Have a look for yourselves at gnovies (http://www.gnovies.com), onderdeel van gnod (http://www.gnod.com).
For example follow this link to look-up The Silence of the Lambs (thriller):
And you will see this movie map appear on the web site.
Gnoovies: Map of Movies (for example, The Silence of the Lambs)
People who like The Silence Of The Lambs might also like these movies. The closer two names are, the greater the probability people will like both movies. You can click on each of the names.

In addition, look for the Map of Music (http://www.gnoosic.com) or the Map of Books (http://www.gnooks.com)
