I saw it the other day, it's absolute tripe of the highest order. The CGI is laughable, they've obviously never gormed how a WW1 biplane actually looks and handles in real life.
Roy Brown wanders through the film, on foot mostly, from begining to end somehow crossing and re-crossing the trenches with consumate ease.
Werner Voss gets the chop without anybody noticing, The Von's last fight never happens he just fades to black sat in the cockpit of his red Tripe, then the flim ends.
The dvd had one saving grace for me... somebody else paid for it!
