That sequence of the Dauntlesses diving in at the end. That's a Money Shot if ever I saw one.
I'm cautiously optimistic. At the very least, from a check of IMDB EVERY named character is a historical figure as far as I can tell, so they definitely did their homework. The only obvious error I see is they used B-25Js for the Doolittle Raiders, but considering that of the 30-odd airworthy B-25s only THREE are early models, that may be a limitation of what they had to work with.
