Hal Prince is anything but a bad director, he directed LuPone in her Tony award winning turn as Evita. He's responsible of such mold-breaking shows as Cabaret, Company, Follies, Pacific Overtures, and the original production of Sweeney Todd. LuPone's concert Lovett was based on Hal Prince's direction but he didn't direct her himself on the concert, but before Doyle took over Sweeney, most people had emulated Hal Prince's staging of the show, it doesn't mean one is better than the other, they are two completely different ways of telling the same story.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
