I saw it this weekend. I enjoyed the staging, very creative and beautiful set and lighting design. IMO Alfred Molina's Tevye takes a little while to grow on you, but eventually it does. Unlike Topol, whom I saw in London, who wins you over two minutes into "Tradition". I think Molina misses some of the subtle touches of Topol, which you can even see on film. He seems to be in a hurry to get through some scenes. I thought the rest of the cast was pretty good, except for the actor playing Motel the Tailor. He is funny and very effective, but is sometimes overdone and seems determined to steal EVERY scene, even when it's completely inappropriate and distracting. Nancy Opel was good but nothing really outstanding, and the new song is mediocre, but mercifully brief.
I liked the show and I am not sorry I sae it. I had a good time and the show is practically foolproof anyway. This revival does not have "soul" as much as it does style. While it will not be a memorable revival, it is worth a visit if you have the time and money.
