Hey, Amazon! "An Education" is not based on a novel by Nick Hornby. It's a screenplay by Nick Hornby based on a memoir -- a factual story, not a novel -- by the writer Lynn Barber. Moreover, Jenny's abandonment of her university plans is NOT meant with consternation by her father. I won't spoil the movie by saying what his reaction is, but your summary is incorrect on a pretty crucial plot point.
I didn't own the CD when I first wrote the review, but I bought it for my wife and it is extremely enjoyable. (So this is a revision.) The original soundtrack material reflects the moody disquiet that underlies the story, and the period music is wonderful, especially the opening theme, a Floyd Cramer instrumental. You will also enjoy Mel Torme, Ray Charles, Vince Guaraldi, Madeleine Peyroux and the new song by Duffy that runs over the credits. It's the kind of pop music that probably dominated the airwaves in London in the years just prior to the Liverpool explosion -- decidedly mature, as the main character hopes to be, rather than a celebration of brash youth, which is what the Beatles represented. This was when cool equalled jazz and chansons en Francais. Very strong.
