I've never seen _Klinghoffer_ and was looking forward to the HD telecast of the opera just to discover what all the fuss was about. That now looks like an event unlikely to take place. There is, however, something I can say about such operas generally (i.e., operas grounded in real, historical events still alive in living memory which would include Adams's _Nixon_ and _Dr. Atomic_) which is that as intended works of art they're a really bad idea from the get-go. The reason for that is that it's all but impossible for a viewer to, at least subconsciously, NOT overlay and/or graft his thinking, biases, and prejudices concerning what was true or perceived as true about the historical case and its surrounding context onto the operas even though the operas themselves may not even so much as have touched on any particular point(s) in question. Once that happens, the work instantly degenerates into propaganda (agitprop) and so becomes, poetically and aesthetically, of little value or worth in its totality as an artwork. Such was true of _Nixon_ and _Dr. Atomic_ (the latter of which two operas has some sumptuous and genuinely beautiful music) both of which operas I did see. Opera creators would do well to stay away — far away — from involving themselves in the creation of such operas — unless, of course, it's their intention to create such Brechtian-poisoned crap.
