Not covered in this article strangely, but kitsch is the most powerful when its genuine. I see the calendar of cats doing yoga poses and it only brings me fleeting joy, its trying to be kitsch, and it doesn't feel like the "artist" really put the effort in. When they do I can feel it, and for some reason I'm weirdly inspired by it (probably because if I really tried, I'd put out something like that).
I know movie examples way better than attempts at painting or sculpture. I watch bad movies weekly and its one of my favorite indulgences. When we watch a Neil Breen movie I can feel the genuine attempt to make a movie that says something...and failing spectacularly at it. When I watch Sharknado I see a pretty cheap attempt at a gag that might delight me for a bit, but feels empty in its attempt to make real entertainment. Ed Wood movies have that sort of charm, they score F's in every department from acting to sound editing, but you can feel the energy of the cast and crew as they try to make something special and fail. Hallmark Christmas movies are probably the best analogous thing to the sort of kitsch we think of when we use the word, they're ostensibly pro-Christmas spirit with a middling cast and plot line, but usually there's an element of genuine attempt to make something your 50-year old aunt would enjoy while she sips on egg nog. Personally, I love that shit.
