I really liked it as well. While I was closely watching results between Obree and Boardman during the 90's I had no idea until recently about the mental suffering Obree had gone through. It was a decent film even if you are not into cycling, I can easily forgive some un-authenticity in a drama.
I am re-reading "One Gear, No Brakes" which is Canadian Track Cyclist, Lori-Ann Muenzer's story of beating the odds and capturing the Gold in Athens. Seems to be a common thread, alienation, determination and leaving it all out there.
