I would say this is a great Oklahoma! for people who don't like Oklahoma!, whether because they find it old-fashioned, or problematic (in terms of race, gender, etc.). It's also a pretty good Oklahoma! for those who are open to seeing a very different interpretation and won't mind if the show doesn't give them all the things most versions do.
It is not a good Oklahoma! for those who just want to see a classic production done the way they remember. Although to what extent publicity and press can make more people who might originally want the classic version actually be open to a new interpretation, I'm not sure. Sometimes people like to fool themselves into feeling hipper than they are; such people tend to read the NY Times to know what to think. But then again, it's Broadway, and we all remember what happened with the Spanish lyrics in West Side Story.
But to answer your question, I'm having trouble of thinking of the last time a Bway revival of R&H veered THIS much from a traditional presentation. [Slight spoilers below]
The smokehouse scene, the final scene, and oh boy, the ballet...this isn't your grandpappy's Oklahoma!. (I won't provide more than this here, and I'd recommend avoiding too many details if you are planning on seeing it).
