I've tried to convert one of my sisters by showing her Yuzu's programs. While she acknowledges that Yuzu is far superior than the other men (she particularly pointed out Yuzu's elegance on the ice), she prefers Javi. I wouldn't call it a failure since I was still able to make her interested figure skating.
Although I wouldn't say my mom likes fs, she has noted the difference of Yuzu's skating compared with the others. I was re-watching the final group in the WC 2017 at that time. She said that Yuzu's jumps are light and looked effortless.
I guess I have more work to do.
