Between the British accent and the background noise, I could not understand even 1/2 of the dialogue. Also get to know how to identify the German planes from the British. It is very hard to know who to cheer for. This movie definitely needs subtitles. I traveled 15 miles to see it in IMAX after seeing all the good reviews. The sound was so loud that it was annoying but it still did not help me understand what the main characters were saying. What a waste. This director is too full of himself.
