I'm not fishing for spoilers, but let me say this: one of the distinctive things about Hammerstein's librettos is that he is aware that change--even happy endings--require sacrifice. Julie pays the price way back in the 1920s in SHOW BOAT. (She quits her job and disappears, so Magnolia can work instead.)
By OKLAHOMA!, Hammerstein had sharpened his focus: the happy ending of the show--including the "brand new state"--is only achieved through the death of Jud, even if no blood is splashed on the newlyweds. The helpless bigot, Lt. Cable, is sacrificed in SOUTH PACIFIC; the old-fashioned autocrat, the King, dies in THE KING AND I.
This is a running theme in Hammerstein's work, so I'm left to wonder when I read descriptions of this new interpretation. It just doesn't sound all that new, except that it seems to resist attempts to perform OK! as a traditional musical comedy.
In fact, the death of Jud in a musical was quite shocking in 1943 and a new term, the "musical play", was invented to described the R&H shows. So OK! was understood to be a new genre, even 75 years ago.
