How can a Spongebob Musical be amazing?! With this crazy and dark world, this is the ultimate escape and pick-me-up. Brilliant and so so damn uplifting. I say this is a lock for Best Scenic Design, Best Direction, Best Sound Design, and Best Lighting Design.
The whole cast was incredible. No matter how underwritten their characters were (believe me, there were a lot! More on that in a sec), all of the actors pulled it off. Every single person was a star, but Ethan Slater (Spongebob) and Gavin Lee (Squidward) were so spectacular and they deserve every award and nomination that will come to them. This is the perfect Broadway debut for Ethan. He is doing fantastic work, character-wise, vocal-wise, and physical-wise. His energy and sweetness are contagious. Gavin's acting for Squidward is fun and spot-on, but his dancing in I'm Not a Loser is phenomenal. I say both of them could easily win Tonys, depending on the competition. Other favorites are Kelvin Moon Loh (his bass is so cool!), Wesley Taylor as Plankton, and Stephanie Hsu as Karen. I like Carlos Lopez as Mr. Krabs in the cast album, but Brian Ray Norris's voice is so uncanny as the one in the show. Like others have said, Jai'len is amazing as Pearl! Can't wait to see what she does next.
My problem with the show is the book. They do have great jokes that are original and from the show (The "is mayonnaise an instrument" line from the TV show was met with cheers). The FIDDLER ON THE ROOF reference was brilliant and I was laughing for a solid minute. They have so many plots together that is a somewhat jumbled mess. They did fix some of the problems with cutting a lot of Patchy time (I still think they should have cut him altogether) and thankfully expanded Plankton & Karen's roles (Wesley and Stephanie are so excellent and hilarious together! BIG GUY!), but the structure is still a little bit complicated with Plot A, Plot B, Plot C etc. I also thought some of the characters were extremely unwritten. Patrick is my favorite character in the TV show and I thought he was so badly-written. I don't know if Patrick was too whiny or if something was missing from him. But, like I said: the actors made every role work. Danny nearly makes up for the writing; he is really funny and quick as Patrick. It doesn't help at all that they cut Patrick's verse in BFF. I also don't like that Mr. Krabs doesn't change. He may recognize his daughter more, but he still prefers money over her and the town at the end. Also, I also thought some of the politic jokes and the anti-prejudice messages were weird and forced. It was the show trying to be hip and it doesn't work. At all.
But, the show is really a great time and it's something that we do need right now. Ethan's performance is especially not to be missed. I highly recommend doing your Spongebob research before seeing the show because you won't get some things like Patchy.
