Much like Cavandar is Coming in season three ( staring Carol Burnett and Jesse White) Mr. Bevis is the story of a guardian angel trying to make Mr. Bevis a sucessful person but by a very narrow definition .It's the idea that money,power and regognition makes people happy. Mr Bevis is an individual who does't fit that definintion of happiness so there must be something wrong? Following this forumla it's always the guardian angel that has the bigger lesson to learn. Mr Bevis is not happy trying to fit in and be " successful " and is happy to return to his own life and that's the point he's happy his way and that makes him a success.
