Thought it was ok but, as usual with Hollywood hype, I thought it didn't meet expectations. That being said, if I could ever love a machine, it'd be a Mk IX or XXIV Spitfire. It was worth it for me just to see a movie with them in it.
Like the seeing the same event from the different perspectives, but really didn't portray the multitude of participants nor the duration of the rescue. I agree it didn't live up to expectations.
