Kudos on including 28days/weeks later. Definitely my favourite for their realism( relatively speaking, of course). Though I found your omission of George A.Romeros "of the dead" franchise a bit bewildering. And when it comes to horror, I find the Japanese films far superior( ringu trilogy, ju-on:the grudge), just never mind the remakes. And I do think Saw doesnt deserve its lofty position. Its just gore for the sake of gore.
