Los Sin Nombre is a truly terrific Spanish horror thriller capable of scaring the viewer unlike the dozen of American late-90s horror boom flicks that have flooded box offices for way too long. Spanish director Jaume Balaguero uses old fashioned lightning tricks as well as modern editing to a good extent. Colors and mood are borrowed from David Fincher and the plot from Roman Polanski's masterpiece - Rosemary's Baby. Taking bits from here and there, Balaguero combines the elements to create a fine piece of cinema, definitely worthy of all it's Hollywood counterparts and more. Now, let's just hope that Balaguero gets invited to do his first Hollywood flick like his colleague Alejandro Amenabar (Tesis, The Others) as there's never enough fresh ideas in the boring US horror industry.
