Thanks. Generally speaking, I feel that revision as far as actual rewriting of text should die with the creators. And as for radically revised interpretations that do NOT change the actual text, I like to think I'm open-minded enough that I have a problem with those only when I feel the reinterpretations result in an show that goes strongly against the spirit of what the creators intended. In that specific regard, I would say the Fish OKLAHOMA! was even more egregious than the Paulus-Parks PORGY AND BESS (though that was certainly egregious enough).
I've seen lots of wildly new interpretations of Shakespeare, but I'm not sure I can think of one that I would say went strongly against the themes, characters, etc. that the author created. (I abhorred that OTHELLO at the New York Theatre Workshop, but for other reasons.) And I'm not sure I've seen any production of Shakespeare that featured any actual rewriting of the text. Cuts, I think, are a different issue.
