Just saw this tonight as well and came out positive on the whole, though it did take me a little to settle into. There's a lot of abstraction and I think I had to just convince my brain to see it that way (I've never seen a production before but I know the score fairly well). But that abstraction is also why small details like the years and anachronisms didn't bother me (though I do find it curious that they were changed, because if they don't matter then why make a point of it being that way?).
Nicole is absolutely giving an outstanding performance. I can't say that every single one of her choices landed with me but it was just thrilling to see (even from the back of the balcony--thank you projection screen). She's so fluid and manic and it's exciting just to see what she'll do next even if you don't ultimately agree with it. Her singing too is incredibly modulated, she plays around with timbre and placement and the deliveries manage to feel fresh while suiting the production they're in (though I'm sure certain purists will quibble). I'm having a VERY hard time imagining Mandy doing what Nicole does, so I'm curious if it'll be reconceptualized for her (I can imagine Caroline Bowman coming closer though).
Like I said, the whole concept took me a bit of time to settle into and I found the car chase scene to be laughable, to the point where I was concerned I'd hate the entire production, but thinking back on it now, I think it does add a layer to the show that's playing with general layers of perception. I'd love to see this again, because I think it would take a second watch to be able to fully digest what Jamie Lloyd is doing, but I think there's a lot of smart stuff about the idea of what you see on screen vs what's you portray in real life vs your own conception of yourself. A lot of the aesthetic imitates film noir but I think the show straddles the line between that and straight up camp/melodrama, so there are still moments that feel overdone. But if anything Jamie Lloyd (and his lighting designer) know how to create gorgeous stage pictures with shadow and light.
The main part I think that didn't really work for me was Betty. Pretty much the whole Hollywood cast (including Joe) are directed to essentially keep stony faces and it works once you realize that this show isn't going to be presented like other musicals, but it doesn't quite land for Betty being somewhat of a newcomer to the scene, and it makes it hard to understand how much Joe really does care about Betty (so Too Much in Love lands with a bit of a thud). In general most of the characters feel like they're at a bit of a remove, which does help Norma feel more vibrant (maybe overly so in some instances), but it's an interesting choice when taken with the whole of the show.
The sound design was a bit rough from the balcony. I could hear most things fairly clearly until there was an ensemble number and then it was just mush. But the bigger problem was that it just felt blaring, everything dialed up way too high. It could be thrilling in moments like the Sunset Boulevard reprise and the final few scenes, but I'd rather they save it for those moments. The images on the screen were a tiny bit distorted from the angle, but I was concerned that the top would be cut off by the proscenium arch and that wasn't an issue at all! Though I think front mezz would probaby be the ideal place to sit.
I can't say I loved this as much as others in this thread, but half an hour into the show I could already tell that I'd want to see it again, both with Nicole and the other Normas (also Jimin Moon as an understudy for Joe is quite intriguing too!). It feels like a show where the "meaning" behind it might change with each watch or where there might always be something else to be gleaned.
