Watch a film with a nurse and they will criticise any scenes involving medical procedures, watch a film with a rugby player and they will criticise any scenes involving rugby being played, watch a film with a soldier and they will criticise any scenes involving using weapons correctly. Every moment of a film could be broken down into parts that displease some specialist or other in that particular field, if the story isn’t good enough to forgive such details then watch something else. Monty Python & The Holy Grail - they aren’t really on horses, they are just banging coconuts together.
