AC/DC after Back in Black (yes I know that's Johnson) is mostly painful. So count me in the 'not really' category

I couldn't agree more
Back in Black is a huge part of the equation. It's the second highest-selling album of all time, the highest-selling album by a band, the best-selling hard rock album of all-time, and the best-selling album ever released by an Australian musical act. Back in Black alone makes a pretty strong argument that the Scott/Johnson transition was the best/most successful major band personell transition ever. Not even taking into account the rest of Johnson's albums, hits, soundtracks, wildly successful tours, and longevity.
