Even the Deadliest Catch episode about the film crew was excellent!
This show is the best "reality" show out there - there is some drama, some censored swearing, etc. But the show has real people, real hard working Americans, and the trials they go through in a particular field.
The show clearly demonstrates the importance of teamwork and camaraderie, and the edginess of someone out of the fold. The humor is well-natured. One of the crew members was in trouble with the law, and when he returned to the ship, the rest of the crew celebrated (with him) by torching his old gear to symbolize his past was behind him. I think that's great!
Mike Rowe does a great job narrating, and the film crew gets incredibly difficult shots in the midst of four story waves. I watch this show so much that my wife gets upset! "Not this show again!!" :P
