For me it's one of the worst things I've seen. Some of the reasons why are
* The set is one of the ugliest I've ever seen. And for all the money thrown at it there's a lack of magic
* The songs are mostly forgettable and I personally don't think a pop score suits the subject material
* The leads aren't that strong, Kelsey was there for cheap laughs. I hated the 'cheers' joke, completely takes you out of the moment. Matthew tries but isn't that strong an actor, and LMK is just a bit bland
* The source material is such a beautiful and subtle film. This tries to be a disney style big blockbuster, and it doesn't suit the story. It's like it's fighting against itself
* The book is weak with the story not working or going anywhere for much of act 1. Plus the fairies joke feels so dated and borderline offensive. This is 2015, and broadway is still getting cheap laughs off gay stereotypes
From the pub song in the 2nd act it does start to come together, but having been bored for the rest of the time it's too little too late. Also at the end with their budget you'd think they'd find a way to hide fans
