I expected so much more from this but it was rather dull and boring.

As a plus, the cinematography and flying scenes were good.

However, there was a total lack of back story, and character development.

I was hoping for an introduction, the British and German Command centres, the rousing call for public help, empathy with lead characters.

There was almost no dialogue, so no story, and there was no great ending

Hacksaw Ridge, Saving Private Ryan etc much better.
