I've seen the original in broadway but I was curious enough and enjoyed the show the first time that I had to see the local production!
One thing was evident... the quality of singing is a notch better than the original! Especially with Rachel as Kate. The puppetting could have been better since in the broadway original I hardly notice the real actors as I was focus on the puppets all the time. Here, I saw some lapses in puppetting... or maybe that's because i'm much closer to the stage this time :)
The production was comparable although I felt the broadway show was more "grand". The local production has made up for it with small changes in scenes and timing of lines.
The cast were great! Everyone was a step up on singing. Performance-wise, it is a split for me with some doing better than the original while the others not but definitely comparable. I definitely enjoyed it and for those who haven't seen it yet... you still have a chance! Don't miss it!
They've posted these samplers of Rachel Alejandro singing. These are not from the show itself since recording is obviously not allowed inside.
