Oddly enough, I just saw a trailer on TV for the DVD. It was enough to put me off buying or even watching it. It has to be said CGI is simply not mature enough for flying movies yet. It simply doesn't look real, you cannot suspend belief if you know you're looking at CGI. Plus they make the aircraft fly like F16s. You only have to look at flying sequences in the Blue Max and VonRichtofen and Brown to see the difference.
Of course I'm biased as both movies were made near where I grew up. Can you imagine being blase about seeing formations of British and German biplanes passing overhead, not to mention casual about seeing dogfights? Well except for one particular dogfight, which I attribute to my interest in becoming a pilot. On the deck it was a duel between two pilots, so close I could see their faces. No airshow has ever come close.
