Ah, TGIF. As a kid, I grew up with that block, as it had some good shows like Family Matters, Dinosaurs, Sabrina The Teenage Witch, and this show.
The story of this comedy has a dark scene for a family sitcom airing on a Friday Night block famous for airing shows the entire family will enjoy. Marty, the main character, dies after accepting a dare from his best friend, Steve, and eats a six-month-old burger. However, he meets a floating head, who reveals himself to be Rob, God's cousin, who states his extreme youth is why they're considering his admission to Heaven, however, Marty must prove himself worthy, as Rob has a mission for him, revealing his friend, Steve, is going through the worst time of his life. Other than losing his friend, his family is divorced and going through difficulties. So Marty's mission is to be Steve's guardian angel, which Marty accepts. And thus, the misadventures begin.
So, this series was created alongside You Wish (the show with the genie) in an attempt by ABC to capitalize on the success of Sabrina The Teenage Witch. So it follows almost the same formula, as episodes focus on Marty trying to use something powerful to help Steve in a situation he's facing, only to end up making things worst. One episode involves Marty finding out he can travel through time and uses said power to stop himself from eating the burger, resulting in Steve and his family eating it, while another focuses on Steve's sister taking a feather from Marty's wings, which grants wishes, with Marty having to seek guidance from Rob to set things right.
It was a good show with the same humor that made Sabrina a hit. Sadly, it never got the success the teenage witch enjoyed due to CBS launching the CBS Block Party (a block whose failure would create an audience fracture that, combined with other reasons, would lead to TGIF's demise), as well as Disney management, caused this rare gem of a show to end with one season making up 17 episodes. This is a good series that truly deserved better.
