I really enjoyed SpongeBob. It was the best adaptation of the season, hands down, and possibly one of the best adaptations in musical theatre. It took a property that, on paper, seems impossible to adapt to live performance and did so with aplomb and a boundless well of creativity. I also appreciated its messages (unlike Jesse Green, I DO think it has something to say, and something important, too!), which is something the cartoon series doesn't really do.
But at the end of the day, it is still held back, pretty much by design, by its source material. A musical based off a madcap, frantic Saturday morning cartoon- no matter how well it translates to the stage- is still going to feel more shallow than something serious-minded like The Band's Visit.
