I don't believe in walking out of a film for the following reason...
'Dancer In The Dark', on the opening night ChannelFour Films offered to give you your money back if you walked out in the first half hour ! I really did consider this as the first half hour is really hard to watch, bad acting, nothing happening BUT THEN...
The rest of the film is amazing, as soon as the first song starts you are glued to your seat and the end is heart wrenching.
A great film.
