Saw the show last night, and, as someone who has seen Cabaret several times, but has never really loved it (as far as Kander and Ebb go, I think Chicago is far superior), here are some impressions:
1. I think it's a really good production: very cool, always interesting to look at, with great choreography. Some directorial choices worked really well for me, others not as much.
2. Gayle Rankin was fantastic, and her "Cabaret" was the clear highlight of the evening. Definitely like Jessie Buckley on the cast recording, restrained at the beginning, then fiery at the end, with a less "pretty" but very capable singing voice, and absolutely nothing like Amy Lennox's over-the-top performance at the Oliviers, which I hate.
3. I thought Eddie was great, as well, and I no problem at all with either his characterization or his voice, which I really didn't get much "Muppet" from, and definitely not Kermit. It's a bit Lew Zealand with the flying fish, but not enough to bother me.
4. Bebe was just fine for me, and that was surprising after hearing that she's the best thing in the show. Her accent was never believable, and I thought Steven Skybell, who I loved, outshone her at every turn. Her "What Would You Do?" was great, but, for me, it was too little, too late, and I left the theatre feeling "meh" about her. I really don't see her as being a contender for the Tony.
5. Ato Blankson-Wood is the clearly the weakest link, by far, and I thought he lessened the quality of the entire show, which is a shame. He's just not in the same league as everyone else.
Overall, I had a fun evening, and would see it again, for Gayle. Like I said, the show itself isn't one of my favorites, so my expectations were already not particularly high, but I was pleasantly surprised by how much I enjoyed myself. I was seated in the last row of the regular mezzanine, which was too far to see faces clearly, but offered a great overall view.
