How accurately does Chris Nolan's film Dunkirk reflect history?

Having seen the film 'Dunkirk' I was surprised to discover that it has been heavily criticised by critics. In particular, the French claim it fails to give adequate credit to their forces. The film was released in India, where disappointed film goers are upset that the Indian forces were not portrayed.

I myself thought it was an excellent film. However, I am aware history gets revised over time, depending on who's doing the storytelling.

However, as Sibelius once remarked, 'A critic has never had a statue erected in his honour.'
