The only show on that list I've not watched is Supernatural - the rest I've watched quite a few times over the years and if they came on a particular channel I was watching I wouldn't feel the need to change it.

I hated The Waltons and Little House as a kid, but had nothing to do with religious overtones (funny but I think Little House was less popular here in the part of the country it was set in than in other areas). I just found them to be boring as hell. Touched by an angel and Highway to Heaven just were just horribly written.

Don’t forget about this weird concept show which totally ruined my view of Jason Ritter

Used to, don't anymore.
Though I will admit "Almost and Angel" is a very funny film, but that is more down to Paul Hogan than the religious theme.
The idea of an angel robbing a MacDonalds at gun point using a KFC bucket as a mask for a 1000 burgers and then distributing them to the poor and homeless just tickled me.
