I think you mean after the run at Steppenwolf instead of the Public. I do not remember seeing what Quicheo mentions about "Where the characters speak to the audience largely as themselves and present the men like exhibits in a natural history museum." Maybe I am wrong but I really do not remember anything like that. I only remember the very long play (even if it was the typical, approximately, 90 mn) and the WTF last 10 mn. or so.
Now, I might go see it just to check it out since the "prologue" might really change what happens at the end. Only if I get a good discount, though.
