See it if you like a dazzling show with fun lights, set, dancing and having the audience play an interactive role. You loved War and Peace.
Don't see it if You like your musicals lyrical or musically diverse, you go to the theater for great writing and lyrics.
See it if You like well-written dark family dramas, Irish accents, strong acting.
Don't see it if you prefer a lot of scene changes and new characters, you can't take dysfunctional families and brutal relationships.
