Watched his "There is only one story structure" and "X-Men: First Class" videos, the guy's a hack. His stuff is extremely reductive, and since he doesn't establish a frame of reference for the journey, he can pick and choose information that fits into his model.

There's a lot of Campbellian keywords and abbreviations, yeah, but there's no sense of why those terms are important.

It fails since he's just talking with authority describing something, but making no effort at all to explain what it is about a story's structure that makes it compelling.
