The series was for years entertaining, with scripts that didn't take themselves too seriously and developed an interesting cast of characters. But, as with the great majority of series, the writing began to decline, whether it was due to turnover in the writing staff or loss of inspiration, to the point that it was a relief to see the final season come to a close. The series began taking itself too seriously, with plots involving trips to Vietnam to fight the bad guys, Magnum's love life in Vietnam that resulted in the birth of a child, and culminating with the absolutely ridiculous finale where Magnum --who had been out of the Navy for eight years/seasons-- rejoins the Navy. It was a terrible conclusion for a series that had been so much fun at one time.
