Good, but not great. Interesting story of survival, but it's not that original. There had been numerous WW2 POW / survival-through-unbearable-hardship movies before this, and this isn't that different from those. Plus, writer-director Bruce Beresford pulls his punches with regard to Japanese atrocities in WW2 - the reality was a lot worse than the movie makes out.
Still, emotional and interesting nevertheless.
Good performances all round.
