I don't get why other viewers thought about the film as a walk in the park and that there should be casualties from the British-led operation, like just how OP the group where. Operation Post Master by record does have 0 casualties on the British side. It was depicted in a comical way to entertain the viewers. It would be boring if the writing clinged to the fact with no Axis casualties though.
I do agree that there are unnecessary scenes wherein they portray Marjorie as badass and not shine with action sequences. She is an actress after all in real life and she did the operation with just acting.
I do not agree with characters not being fleshed out for the viewers to be attached to. If you truly watched the film, the subtle sequences already explain their personalities. With how grim, determined, and focused they are on the mission.
It was straight dark-humored, had great action sequences, and darn entertaining. I will give it an 8.5/10
