Eerie, Indiana started as a Sunday night primetime series that aired on NBC in 1991. It lasted just one season, but that didn't deter Fox from picking up the show as a fill-in for their Saturday morning lineup 6 years later.
Here's the intro:
Filmmaker Joe Dante ("Gremlins") directed the series opener, and had a small hand in developing the series. The ratings must've improved enough when it moved to Fox, such that it enabled the network to commission a new series, Eerie, Indiana: The Other Dimension, which was a mid-season replacement in the winter of 1998, but also lasted just one season. The original Eerie has also aired on Disney Channel, but hasn't been seen anywhere since the end of its Fox run.
Rating: None. Never saw enough of the show to form an opinion.
