Saw this on Sunday, there is still magic there. But not nearly as much as on Broadways. There's a lot that's been scaled back.
As Jen said- the tree monster has been traded in for a less effective but I'm guessing easier to travel preying mantis.
The impossible transformation has a new variation on Cinderella's dress change which is not the same as the Tony version or the Broadway version. It's still effective, but perhaps less so than the other two.
Marie's dress is different- though i think its the same that Judy Kaye is presently wearing on Broadway too. I like it less, but that's just me.
Overall the impossible sequence seems to be very similar though.
The pursuit sequence is where I really missed the broadway production- it just felt a little empty to me. instead of ending in Cinderella's yard where she sings the lovely 'He was tall' it ended inside the cottage and 'he was tall was cut'

. This meant her pursuit costume change into the peasant dress is different too.
The cottage is a little scaled back, the 'prince is giving a ball' scene no longer has buildings. just carts/vendors.
The palace now has chandeliers that move around instead of arches.
The biggest problem that I had with the show was the cast.
I missed the original cast more than I've ever missed a cast before.
Without them, a lot of the jokes that were delivered impeccably now show how weak the book is. Watching someone else in the role of Cinderella just proved to me what a talent Laura is and what an outstanding job she did.
