The acting and singing. SO good. A highly talented ensemble across the board, not just the lead but also the supporting roles and celebrity impersonations. And the book and lyrics; no point in having a wonderful cast without fantastic material.
What I didn't like
Perhaps some of the songs could be polished slightly more to be even better. And even though I understand why much of the music had to be pre-recorded—Fringe, after all—I’ll bet it would be even better with a live orchestra instead of one talented keyboard player.
My overall impression
Wow. Just wow. Best show I’ve seen at the Fringe so far this year. An original concept brilliantly executed. Excellent acting from the entire cast. Spectacular voices singing catchy songs with hilarious lyrics, some with gorgeous harmonies. I can’t imagine anyone other than an actual Scientologist not having a great time.
