The new play Peter and the Starcatcher is a trip in so many ways. It’s a literal trip, a loopy story about the pirate crews of two ships chasing each other for a misplaced treasure possibly aboard one of the vessels. It’s trippy, with a plot centered on something that seems called star stuff that seems to come from somebody’s psychedelic dream and could be used for good or evil or just to make things weird. And it’s a trip in slangy way, with over-the-top characters and a script that plays with everything from the English language to the audience. It’s a little like Monty Python in its wit and silliness, a little like Wicked in that it fabricates a backstory for an iconic one, and a lot like a piece of children’s theater that went wildly awry. It’s also big fun, if you give it the chance.
