I'm pro-Bob Ross because I think he helped demystify art for a lot of regular people who might have never gotten into it otherwise.
IMO one of the biggest problems with creative stuff in general is that people have this horrible idea that there are the talented and the untalented, and if you aren't born special, you don't get to do it and can't ever be good at it.
In my view, having a popular mainstream figure break painting down as a learnable skill sort of helped bring it back to regular people.
