It was good and, generally, stayed very true to the story, which I appreciated. As expected, the aerial cinematography was amazing. Liked the fact they gave the Korean War some attention with a little historical accuracy.
That said, while the movie tried to spend a lot of time on character development - and the characters were likeable enough, it just seemed to be missing something in terms of chemistry or something. I can't quite put my finger on it. It was a bit on the slower side in getting started and, at times, it felt like the producers maybe weren't sure what kind of story they wanted to tell. As a result, they weren't able to tie/transition between some of the story lines as effectively as they probably should've.
Nonetheless, it was still worth seeing in the theater. I give it around a 6.5...maybe 7.
