I've actually been in a military court room a couple of times... not because I ever served, not because I was testifying or charged with anything... but mainly because historian. Sure, the court wasn't in session at the time but. Wow, A Few Good Men found the nicest, prettiest, and best decorated courtroom on Earth.
Top Gun actually did it better.
But, it was based on a true story that everyone that watched Unsolved Mysteries would become familiar with. And the acting is excellent, right down to Tom's impersonation of Jack.
The story is compelling. In fact, it kind of draws you in from start to finish. The message is strong.
You wrap that all up and it makes for one heck of a memorable film.
