I haven't seen any videos of her as Mrs. Lovett but she is magnificent in the recording. Probably my favorite recorded Lovett since Lansbury. The thing is she gets Mrs. Lovett and she gets what Sondheim was trying to do with that show and the style in which the role should be performed.
IMO, she simply does not get Rose or the style of the show at all. Staunton is a brilliant performer through and through; this, however, is a complete miss. And that's fine, not every great actor is right for every role. Let's just hope when we get another GYPSY revival on Broadway it soars to the levels of Laurents' production. The performances by LuPone, Gaines, Larkin, Yazbeck, Fraser (the whole ensemble really), and most of all, Laura Benanti, will be tough to match. That dressing room scene at the end played like an Albee play in the hands of LuPone, Benanti, and Laurents, simply stunning and unforgettable.
