I think I know what you're thinking Nona (it's been 2 weeks since you asked RR so I hope you don't mind if I step in with my thoughts). You're coming from a true artist perspective, but, as you know, we have to keep in mind that the name of Bob Ross's show was "The Joy of Painting". The key word is "Joy"…getting non-painters and newbies excited to give it a try. He wasn't appealing to the professional juried gallery artists who have matured over time into developing their own styles and use of original thought. Rather...
He was appealing to the beginner artist, or the person who doesn't think they can paint, the person who thinks painting is too hard, the person who doesn't have time to paint (Bob completed his paintings in 30 minutes using BIG paint brushes), the person who is afraid to try. He showed people how easy and fun it is and he indeed got a lot of people to start painting and have fun with it. He was also therapeutic. One guy said, "He's more effective than Zanex for relaxation"
The only problem is that most people didn't continue to develop into true artists but rather just continued to do BobRoss-looking paintings because he didn't give them the skills to do that. But he could only do so much in 30 minutes. It's TV.
RadishRose…I don't think Bob Ross was before your time. His show ran from 1983-1994. The last show was 20 years ago. He died of cancer at age 52.
I enjoyed watching that show just to see how it was done. I didn't even bother to try it myself. My artistic talent isn't in painting or drawing.
