I'm not going to give ANYTHING away, I'm just simply gonna say, "This film is something really fucking special."
And while it was a looooong-ish film, at two hours fifteen running time, I still wouldn't have minded some of the missing scenes in the Extras to have been included. They fleshed out what was (at times) a sometimes-sporadic character-stalking narrative.
Big bonus on the disc, the Victorian TWIX advert with its 'sharing an ill-designed driveway' was there in all its full-length splendour. Yay!
