Yeah it's a pretty damn good film. The book is actually a lot better not to diss on the movie in anyway but just a lot more expanded than what a 2 hour movie could do. But he talks a lot more about the isolation....the suffocating heat. The scorned lovers and the hate he got from people who despised the military. The blatant alcoholism that a lot of guys had (or at least using it to get through really hard shit like burying a friend)
For no better terms it just felt very "how it was" which obviously I have no idea about but it just does. Really nails that empty, nihilistic feeling of wartime and the movie does that really well too. Specifically also that environment of watching air power just destroy everything and not really ever being "needed" or seeing heavy combat. Which these guys trained for and lusted after......and then you basically do not see it, and it just drove these guys crazy.
It stuck with me.
