>>16245243She specifically made a video about how she's Tae Kim but better.
Jokes aside, she praised Kim and Jay Rubin in some aspects but stated she wanted to explain the structure of Japanese sentences more clearly as far as I remember. Kim's textbook is still not structured enough, Dolly tried to give a perspective of seeing the basic structure in ALL JP sentences, understanding what types of copulas and particles exist and learning to use them the right way. Just have a template in your head and slap your vocab and grammar knowledge on it so that Japanese starts making more sense. The closest similar thing might be Imabi maybe? I really liked her videos and I migrated to Imabi now.
