Magnum's tortured soul (spoilers)
I was never a huge fan of this show, but there were a couple episodes I found very well done. One involved Magnum being stranded at sea, and having to fend off a shark and face other life threatening dangers. Another, similarly, involved him being trapped under an old plane. This time though, he had to save a fly (symbolically himself) from falling victim to a spider.
However, rewatching it recently has shown me that there is even more depth to his character than I had previously realized. In one episode, he accidently shoots at the wrong person and a woman ends up paralyzed. Okay, it turns out wasn't permanent, and that she was in on the plot against him, but still, for him to have to deal harming an innocent isn't something you normally see on TV.
In another episode, his former wife and child are killed. Well, at least he thinks so, and he goes to avenge those who are guilty. Though, again, things are not as they seem. At least he is forced to face this for a while.
The main character was dealing with dark emotions that are rarely shown on TV, especially for a "hero." I applaud the show (four decades later) for going to these places, and taking these chances.
