From '85 to '92, MacGyver filled a necessary gap on television: that of the action-adventure hero. Basically MacGyver is the Indiana Jones of the 80's, which the show itself acknowledges (MacGyver goes on several archaeological expeditions, including one for the Holy Grail!). Added benefits were the hero's reliance on mechanical improvisations, his aversion to guns, and the large cast of supporting and recurring characters. The episodes tend to get a bit preachy with their "Message of the Week" in the 4-6th seasons, reflecting star Richard Dean Anderson's own personal beliefs.
