The 5 Stars is mostly for the last three plays, all of which really left an impression on me. The Father is well structured, but at times the characters keep repeating the same thing. Miss Julie is very good, though it does leave you with a sour taste at the end. The Dance of Death is a fantastic character study, and perhaps is my favorite play of those first three more "normal" plays. The last two plays are experimentation in psychology and dab in the surreal. The Dream Play is something I hope to see very soon in the future, as the visual of it would be a wonder, but I was disappointed in how it droned on and hammered the same message. Ghost Sonata was probably the best of all of these plays, as it has a careful structure, and doesn't repeat itself too much.
Overall, highly recommended read.
