Others have said it, but I will echo it.
I saw the show in its out-of-town Los Angeles engagement, which ended up being the Broadway cast (after a much-publicized mess).
The show wasn't that strong. It had an over-the-top set, which was the most memorable thing about it. Truly jaw-dropping when the entire mansion interior lifted off the ground to reveal a secondary location underneath it.
Glenn Close was a big movie star and many people were curious to see if she could sing. Her singing was fine, her acting was not. That was a real surprise for me, since I expected the opposite. She was way too crazy from the beginning, leaving her very little room to take the character on a journey into madness. Her final scene on the staircase was nothing short of Grand Kabuki, so stylized it didn't even fit with "musical theatre" reality, let alone reality. "More" was not "more," in this case. It was less effective, in the end.
Still, when they announced Glenn was going to head the NY cast (and in fact, the whole cast was heading for NY, with one or two exceptions), they also announced that Faye Dunnaway would be her replacement. Faye had been a major movie star in her day, but she wasn't a box office draw (by any means) during Sunset Boulevard. The result? Ticket sales fell way off, almost immediately, for any dates after Glenn's departure.
The show was basically a "star vehicle," but not for just any star. It had to be someone the public wanted to see, because the show itself just wasn't good enough or compelling enough to bring in the crowds to see it.
Ultimately, Webber shut the Los Angeles production down when the cast moved to NY.
You had a mediocre show, with a massively impressive and expensive set, and a big star who was fine in the part, but not remotely brilliant by any means. When she left, the show struggled. Then it limped along until it closed.
Fade to black.
