It's been a long time since i've watched this program, 15 years i'd say. One thing I can say is it's just like I remember, just as heart warming. Michael Landon stars as Jonathan Smith, an angel sent to earth to help those in need find their way. Not as preachy as it sounds believe me. Each episode is infused with a great story and a moral to accompany it.
It ran for 5 seasons, finishing in 1989 shortly after co-star Victor French who plays police officer Mark Gordon died of lung cancer. Most believed that Michael Landon decided to end the series after Victor French's death, but by the fifth season the ratings began to fall, and most agreed that the show had run it's course.
All good things must come to an end. Just enjoy the journey.
