This movie provided the long-awaited payoff of the boys learning Perry's secret, though it ends with a surprising twist regarding his future with the family.
Whether you are a longtime fan or a newcomer trying to understand the hype, Across the 2nd Dimension is essential viewing. It is funny, heartbreaking, and musically brilliant. It proves that even in a multiverse of infinite possibilities, there is only one set of stepbrothers and one semi-aquatic egg-laying mammal of action who can save the day.
