Historical fiction
One thing I find difficult to tolerate is how a film can start out saying something like "This is the true story" when it is a story based on fable, legend, mythology. No real historical bona fide proof, just theories. Do away with such nonsense and give a film that is entertaining without trying to justify how historically "real" it is.
And for some reason, I cannot stand Ray Winstone in any movie he has been in, just my personal point of view.
As far as the film goes, it is so so. I can watch a film I like several times over, this one, just once.
