Other than the stupid trailer cut and sounds, this looks great. Tom Hanks is pretty damned good in dramatic roles like this, and I love this time period (not for the carnage and incredible death that ensued, and certainly not to glorify war) and the incredible struggles that the world went through. Such a transitional period that people are seeing more and more through the foggy passage of time.
I used to work for the Canadian War Museum in the dress and regalia conservation department, and one of the most incredible things for me was not just touching and reading about the history of the things I worked with, but the smells. It makes things so much more "real" to add that aspect, and I really wish movies like this could include things like that.
