See it if you want to see a very restrained version of Hamlet with a nearly full (but thin in ability) cast in a great setting.
Don't see it if If you like bigger production, more energy in your Elizabethean drama and the supporting roles to be performed well and cast well.
See it if You like Shakespeare in the open air in a great location (Castle Clinton) performed by semi pro actors of high talent. This is great.
Don't see it if You are not a fan of Hamlet and you don't like helicopter noise!! But you will miss a treat.
