Grant Drager and Sophie Brown in Flight of the Lawnchair ManPeppy, cheeky, and somewhat unsatisfying - though in ways that are rarely the fault of its current Timber Lake Playhouse presentation - Flight of the Lawnchair Man boasts a friendly spirit, a number of witty and weird diversions, and a brisk running time, clocking in (with the intermission) at a mere 105 minutes. Yet for all of its strengths, and unlike its determined hero, this musical comedy never really takes off. Director Chuck Smith's production is ingeniously designed and energetically performed, but the show itself is a little bit You're a Good Man, Charlie Brown, a little bit The Wedding Singer, and a little bit Bat Boy, and about as stylistically awkward as that description implies.
