Saw this last night at the Pantages, after having seen the Mendes production originally on Broadway with Cumming & Richardson (stunning), and then again a few years ago with Cumming & Williams (meh). Unfortunately, this touring production falls towards the lower end of the scale....
I actually quite liked Andrea Goss as Sally. She was far better than Michelle Williams. (At least her accent remained in place throughout). And most of the supporting cast was fine. Even Lee Aaron Rosen as Cliff (who has to be one of the blandest protagonists in the history of musical theater).
The problem -- for me -- was with Randy Harrison. Now, I never watched the U.S. version of QAF, so had no pre-conceived notion of him as an actor/person/persona. But he just came off as lightweight, superficial, and far too young & pretty. There was no edge to him at all. Sure, he snarled & leered & groped & prowled -- but he just came off like a little boy playing dress-up for Halloween. (There was, however, a huge ovation for him at the curtain, so make of that what you will...)
I don't know. Maybe I'm just over the Mendes CABARET. There are hints that Celebration Theatre will be doing their own version next year here in L.A. If it's half as good as their current THE BOY FROM OZ, it should be worth seeing. One of the best CABARETs I've seen was done recently by the Crown City Theatre Company in Studio City. With an excellent 11-person cast, the director found a new approach to the material which was different & imaginative -- until he blew it by having "Maybe This Time" sung by both Sally and Fraulein Schneider (which I could handle) and placing it at the end after "Cabaret" (which I couldn't). Still, up until then, it was perfectly marvelous. If interested, you can check out this short clip reel: https://www.youtube.com/watch?v=svhIQjeDIW8
