Dc Monster I'm A Huge Fan Of Hard Classic Rock, But I Don't Dig The Brian Johnson Era Of AC/DC. Is This Normal?

I'm a huge fan of hard classic rock, but I don't dig the Brian Johnson era of AC/DC. Is this normal? - dc monster

Here's the thing. I am not a monster by AC / DC fan from the beginning, but I prefer the 70 albums of Bon Scott and older at the time of production of Brian Johnson Band. I also believe that Bon had a better voice of Brian. I like Back In Black, however, is anything but that. Is this normal?
