Whether a project is large or small, it doesn't matter much to me as long as I feel I can serve the story as best as possible.
What I think is great about Pippin, specifically, and I wouldn't make this generalization about all musicals, is that it is about how we tell stories and the way stories are very subjective. How we tell some things and leave other things out in the way The Princess Bride is or The Wizard of Oz is, which both have a framing device.
In many ways, I think I'm a good person for it. I mean, I'm not a musical theater dude. Or rather, I don't watch everything, and love everything, and have every album. The ones that I love - like I've seen The Wizard of Oz a hundred times. West Side Story I love. I love Singing in the Rain, I love White Christmas. I love the Dennis Potter ones like Singing Detective and Pennies from Heaven. I love Sondheim.
All the more a cheesy musical seems fake, so it requires a level of honesty to be injected or an acknowledgement of that which is fake and fun about musicals, and it isn't necessarily escapist. Like there are great musicals like Once, which feel very almost like a mumblecore musical. I love Once. It's great.
