There are now SO many of these "oldies but goodies" channels.... We don't have "light TV" but we do have "Me TV" which also is an oldies channel.
It's a cheap way to get programming..... AND I think there is so much HORRIBLE stuff on the 'tube these days, that even the low-budget, really OLD ( and pretty meaningless) fluff of a generation or two ago seems like a great alternative.
Confession: My wife loves the Hallmark Channel stuff (there are 3 or 4 Hallmark channels now). Very fluffy stuff! But I have to admit, the QUALITY of the productions is better than most new programming, even the acting is often better. Hard to believe this is all VERY low budget stuff (I think Hallmark is owned by Universal). AND the values are mostly okay. No extra-marital sex, no teen sex, no violence, no bad language. Yeah, they produce like 100 movies that are IDENTICAL (only the names have been changed) but it DOES shine a bit in a dark sky.
