Yes, Nietzsche was pissed off on a grand scale by Parsifal. (Though there were other reasons for his fallout with Wagner, too, notably his unrequited crush on Cosima.) The trouble with Parsifal for the Fanged Four is that it did not get performed outside of Bayreuth until 1912 (and then in Monaco, of all the places*g*), and in Bayreuth there would have been daylight.

I still like the idea of Angelus going Misery on old Richard. Though Darla would argue that the scenes between Kundry and her darling boy make it all worth it.*g*
