yay, I've missed these forums.
Looks fine to me, god forbid anyone makes a movie about anything WWII related. The film releases in Jan 2012, and I can say for certain that most of those Special FX shots aren't final, the sound design has been done by the movie trailer people with stock SFX, so those will also change in the final mix.
For action and pace, some of the scenes may have been sped up slightly time wise so they could fit the shot into the rhythm of the trailer making the FM look a little strange.
A 2 hour movie will never fully capture 100% of the details of WWII, that should be assumed first off. Band of Brothers did a pretty good job telling 0.0001% of Easy company of the 101st, and that was a 10 hour mini series.
My final thought on the matter is; this film could inspire those who have no idea who the "Red Tails" are to pick up a book and read all about them. Think of it as a catalyst agent to a long road to becoming a "know it all" negatron like some people.
