This is just a bit of fun, brought to my attention by Phil Bradley on his blog. As he points out, it is not a search engine, but a discovery tool.
Enter a film that you like, and it will attempt to suggest others that you will like. I tried Lars Vons Trier’s ‘The Idiots’ and it suggests ‘The Truman Show,’ ‘Fight Club’ and ‘American Beauty’ amongst others – well, I like one of them at least! It also presents ‘nano genres’ - three word summaries of the film that you entered. ‘The Idiots’ is summed up as ‘thought-provoking happiness’ and ‘morality moral shock.’
