I saw it last night. It's pretty cool, actually, and for the most part it's realistic, and definitely a fun thing to watch. It was good to watch in a theatre because some of the visuals need that kind of space, but I definitely could have done without some of the audience members. Overall it was fun, and a little inspiring (in a "these guys are better at doing this than I am at doing anything" way) and I think tasteful.
As far as it being propaganda, well, yeah, I guess, but in the same way Usain Bolt is propaganda for running. It's not fear-mongering, it's a demonstration of capability. It's more like the fly-overs at football games than the talking heads on the TV.
