This effects not only the movies we see, but also influences which movies get made in the first place. There's little telling what kind of anti-war movies we might have gotten, which withered on the vine because producers knew it wouldn't be possible to make the movie on a reasonable budget to the standard audiences have come to expect (e.g. real aircraft instead of mediocre scale models or CGI.) Try making an anti-Navy response to Top Gun; you won't get access to real fighter jets so your movie is doomed to look like second-rate shit, while simultaneously requiring a huge special effects budget to even get close. Bigger budget for an inferior product is a recipe for a commercial failure, so it just doesn't happen.
