I've never before seen a movie with such an exact-paced build-up to a very dark and sombre ending.
From what I heard, they concentrated more on the storyline than on the sex scenes, but in this case I think they missed the plot.
I might have to read the book now to understand the movie.
P.S. I also never realised that if you click & drag the elapsed time scroll 'dot' upwards, that you can actually reduce the scroll speed when you drag it sideways.. Mmpphh, Never too old to learn it seems.
