I saw and read the play, "The Long Christmas Dinner," and loved the way Wilder goes through four generations of one family, 11 members, and uses entrances and exits, set and props to indicate the passage of time. I give it four stars.
"The Happy Journey to Trenton and Camden," I give three stars after seeing it and reading it. I like that Ma Kirby , the voice of family authority, holds the family together, brings spiritual values into their lives, and shows strength in times of adversity.
I have not read the other plays.
