I really don't know what to tell you. I was not crazy about Tunney's replacement. Justin Guarini was a little scary looking as Will, he never blinks when he sings

Even "Favorite Son" was replaced by a white guy who did not have the muscles or chops for the part.
Pretty much my sole reason for still going is to be in the presence of "his greatness"

It's different if you remember the original (fantastic) cast and compare it to that. Don't get me wrong, I still enjoy it, but every time another original cast member leaves it loses something.
I would say if you are not going to Broadway that often maybe you should see something else - we are going to see "Baby It's You" on 4/23 and "Jerusalem" on 5/1. I really think you would like "Rock of Ages"
