There is an attempt, near the end of the show, to add meaning and depth to the story’s otherwise surface-level emotions. Eventually we’re told that the things we’re attached to from the past keep us from living in the present, but the notion isn’t woven into the text or explored throughout the play. It arrives way too late, with the impact of a Hallmark card. Still, “I Need That” will prove satisfying for those looking to be entertained by DeVito and his daughter. He brings real joy and laughter, and there’s real value in that.
