I really liked him on the short-lived “Aaron’s Way” where he played an Amish farmer who moved from Pennsylvania with his family. IIRC, his son abandoned the Amish lifestyle, moved to California, started a farm, got married, then died in an accident. Aaron (Olsen) took over the farm for his daughter-in-law who was also pregnant with his grandchild.
One of those “fish-out-of-water, clash of cultures” shows that didn’t last, but should have.
