I saw the show last night and I'm a bit dumbfounded. I truly don't understand how such vivid source material could lead to a musical that misses the mark by so much. The book and movie(s) provided images of so many possibilities and this just falls flat on it's face.
The sets are abysmal for a show that centers largely around a candy factory. You'd expect bright colors and contraptions. This is Willy Wonka's factory, not a place that produces 75% cacao organic chocolate! It lacks the spark you assume workday be there. The scale of the sets also felt very off, as if the dimensions of the scenery and props were not measured correctly. The Lunt-Fontanne is a decent sized theater, but many pieces, to me, felt like they were intended for a theater with a smaller stage. I felt similarly about the costumes--I expected over the top and it wasn't the case. Some of the ensemble costumes look like unfinished prototypes. They weren't enough. I also figured we'd have some kind of cool Violet swelling up costume or effect, but it was a bit of a let down. It seemed too small.
The cast does the best they can with material that disappoints. Borle is okay as Willy Wonka. Not great, not bad, but okay. It felt lackluster. I don't think it's the best written part he's had, but I think it needs a little more oomph from him. His performance in Falsettos was far superior. People here have mentioned disdain for Violet,Mike, and Veruca and I totally agree. Their characters are highly unlikeable, but they shouldn't be cursed with awful music. I think Mike Teavee's song might be the worst...it just goes too far and away from the world established by Charlie and his family.
I left the theater feeling completely disappointed. A show that should have potential falls entirely flat. I kept thinking there's some big song or set piece or effect that could save the show, but sadly, that never comes. It's completely understandable why people were asking if the set was still waiting for a major element to be delivered. It's that underwhelming.
Some shows do well with minimal sets and allow the viewer to use their imagination. Because of the legacy of this source material, you don't expect Charlie and the Chocolate Factory to be "minimalist" in any way. I expected bold and creative here, but sadly, that never came. The show is a mess and a letdown.
