OK, I'll try to comment mostly on the music cause enough has been said about this movie. I think it's a very watchable action movie (despite some flaws). Yes, it's not too realistic, but such a movie would most probably be boring (check how it worked out in The Finest Hour). Yes, it's not too deep, but come on, which action movie is (e.g. what's so deep about characters in Die Hard? nobody complains about that and they shouldn't)? Please take into consideration some other action movie involving the SEALS e.g. The Rock - the unwatchable Michael Bay/Nicholas Cage exploding blockbuster escapade which somehow has over 7.0 rating.
The most positive thing about this movie are the great action scenes which look pretty realistic (the gunfights in Beirut, for example). Nice use of the camera (although it looks a bit 'TV' in some places) and very authentic looking scenery (with some nice details, e.g. like that destroyed Israeli M113 in the background).
But the amazing thing is (personally) one of the best music scores in an action movie ever (which unfortunately I can't seem to find anywhere). I mean, Sylvester Levy really did his job right. Every time they head for action, they are followed by excellent instrumental scores which give this film and the scenery much more depth (my favorite one plays when they are running for the shore). Unbelievably good.
So, must have seen it a couple of dozen times and still like to watch it for the above reasons. It's not a deep movie, just good war action and great music. I enjoy(ed) it. Maybe you will, too. Personally, I'd rate it as 6, objectively at 5, IMDb 7 at least (should have more since atrocities like The Rock get 7.3 average).
