As a passionate cinephile I get intensely annoyed when modern directors steal the ideas, situations etc., from great, and even not so great films from the past. 'Signs' is, in effect, little more than 'War of the Worlds' re-couched in a family environment that is reminiscent of 'The Birds' with a splash of 'The Wizard of Oz' thrown in. One has the idea that M Night Shymalan might claim that is film is some kind of homage to these films, but that is nonsense. It is a load of tosh (English slang for rubbish), that is interesting, up to a point, all the time it is 'about' crop circles, and disintegrates into ridicule when it becomes an apocalyptic vision. 'The Sixth Sense' was clever, well-constructed and thoughtful. This film is none of those.
