Well, yeah, it's nitpicky. But I think I get what they were meaning - if they can't get the simple things right (like having an actor stick a cigarette in his mouth) - then how many of the *big* things did they miss.
After chewing on this thread for awhile, I decided that if Lucas spun this movie as "A Bunch of WW II pilots, kicking butt and blowing stuff up", and had it star a handful of big-action-movie actors .... I'd probably have been OK with it.
But, to put it as a historical / biographical piece, when from the appearance of the trailers, it's neither ... well, then, I'm going to miss it.
And, regarding "nitpicky" ... a long, long time ago I watched the 60s barnburner "The Battle of the Bulge" with my Grandfather. ....He "Caught It on It's First Showing", as he blithely put it.... Afterwards, I asked him what he thought. He said that, "It was a fine movie, but no one looked cold enough." It was insight that I'd never even once considered.
Now, I judge most wartime, grunt-type movies, by how cold, wet, dirty, and/or miserable the actors look. Funny, no?
It seems funny at first, but after thinking about it for a while it does make sense.
Upon thinking of past films I have seen, I have done that. One recent film was In The Land of Blood and Honey.
And strange how in that movie, Belgium looked just like the California high desert ... like around Ft Irwin.
