Before attending Friday's performance of the Playcrafters Barn Theatre's A Wrinkle in Time, I knew very little about Madeleine L'Engle's beloved science-fantasy novel, save for the recent movie trailer featuring Oprah Winfrey. And as I watched the near-capacity, all-ages audience file in, I could sense an air of joyful anticipation, not unlike the one you might find at the screening of a Harry Potter movie. But by the end of the performance, I felt confused and more than a little disappointed.
