If you like this person's taste, follow him or her!
See it if You crave relevant drama from a master who knows his subject - tyranny - first hand: the reality of oppressed life and ambiguity of action.
Don't see it if you prefer "on the nose", "tyranny is bad" plays.
See it if you are a friend of one of the actors.
Don't see it if You don't like rants against our ranter in chief, declaimed without subtlety, humanity, humor (except for the "flaming gay" shtick).
Also Where is Colbert when you need him?
See it if You like good writing, want to see an acting tour de force (Pan). There are some very intense moments.
Don't see it if The play is perhaps 10% too long, some of the acting is a little limp, and the endings of the various conflicts are somewhat forced.
See it if you like a fluffy comedy and have a couple of hours to while away.
Don't see it if It isn't one of David Ives' best work, so if you've seen a good production of The Liar, you'll be a little disappointed.
See it if Diaghilev and Nijinsky fascinate you and you are happy to see them on stage.
Don't see it if you like a play that is emotionally compelling, or funny, or goes deeply into the souls of some very interesting persons
See it if you agree with the sentiments (not hard to do - collectivization in Soviet Union was murderous)
Don't see it if You are expecting a sensitive performance of what might be a good play
See it if You like watching Katherine Chalfant do what she can even with limp material.
Don't see it if you ever read "When Wendy Grew Up", Barrie's own much more affecting sequel.
See it if you would like an interesting take on Hamlet, speak Farsi, or want to connect emotionally with the characters.
Don't see it if You don't know the plot. Several crucial scenes are in Farsi - of course no problem if you speak the language.
