Worst Magnum PI Ever
20 February 2016 | by LumpyMusicSee all my reviews

This single episode is the worst of the entire series for one reason. The old gangster character, played by actor Michael Gazzo, annoyingly SCREAMS and SHOUTS during the entire episode. It's not just unneeded for the plot, it's physically annoying to have to listen to that gravely, shouting voice for the entire show.

The girl's probably the least glamorous of all the Magnum fem stars.

The one way antagonism from Higgins toward Magnum is still pretty beyond reasonable. It's beginning to ease. In the previous episode it was a little less strong. But the characters generally haven't found their individual niche parts in the show. TC's still overweight. Magnum still walks like he's doing the Tango. It'll resolve later in the series, I hope!
