Looking at the Fringe guide, I wondered how C.S. Lewis’ best known work could be condensed into 42 minutes. Well, the production was actually 30 minutes. And it felt long. But I’m about 15 years older than the target audience and I left my stunt children at home. With no ability to gauge the play’s success on my own, I inferred from the sporadic giggles behind me that the Adventure Theater production had achieved its goal: to entertain the kiddies.
