Ok, this is definitely a typical macho movie where the guys get to flex their muscles and show off their superiority but it's also a very enlightening movie, never knew much about the dangers divers had to go through till I watched this movie.
It's also a movie for us gals to drool and the hunks in this movie, the guys certainly worked out well to show off their well toned bodies here. One of my fav scenes in this movie is of them in their birthday suits standing at the full length window looking out into the sea, phew, the temperature in my room rose to an all time high! hee hee
As the rest have said, it's mainly about the importance of the buddy system in this movie and about male bonding and working as a team and having faith in ur team.
I'm looking forward to watching the dorama once it becomes available in vcd later this year.
