Query: The American play at its best

Eugene O'Neill is definitely one of the greatest playwrights of all time. I saw Long Days Journey Into Night a few years ago and was just struck by the true dysfunctional family that hearkens to society of today.Moon takes a character from that great play, James Tyrone, Jr, (who incidentally is O'Neill's brother -- the entire play is autobiographical in nature) and draws readers into the tragic world of the Hogans, and Tyrone. The raw emotions of the characters become apparent with the read -- a difficult thing to do for readers if they have not seen the play -- and also is startling honest about how jealousy, fear and desperation all meld into one.Definitely a must read, if you want to consider yourself in the know of American literature, but Moon does at times seem trying, with blatant symbolism(the moon is quite noticeable throughout the play) scratching at the reader.
