I saw this last night. Bought my seat as soon as I could when they were available and sat in K2, great side aisle orchestra seat. Enjoyed the music and Katrina Lenk was amazing. Agree it is slow-paced and I found myself thinking about what I was going to eat after the show let out, even though I wasn't particularly hungry. This was my 9th show in 6 nights, so maybe I was just tired, but I thought this might be my favorite show, so I saved it for last.
I thought that the accents were hard to understand at times, and sometimes inconsistent. It made it a bit distracting. I got confused by two characters dressed similarly in the soft lighting, so wasn't sure what was going on in those scenes. I couldn't understand anything one character was singing, even though he didn't sing with an accent. I think maybe he wasn't loud enough because it was a quiet song, and when he had a moment when he was emotional and loud, I could tell that he had an amazing voice, but also couldn't understand what he said.
i enjoyed the humor, and it was nice to see Tony Shalhoub. To me, it was sweet, cute, delightful at times, touching. Loved the music, so I'm sure I will listen to the cast recording over and over once it is released. Might consider seeing it again at a discount at a later date if I have an empty show slot.
