I'm an opera buff, and operas are full of sex, blood and death. It may help to know the librettos of the operas the arias are from to really appreciate this film -- my mileage is very different than Tug-3. I am a classical music lover, and I liked this film.
I loved Ken Russell's "Nessun Dorma" segment, and would actually like to see him produce Turandot, because opera is supposed to be overwhelming, truly multi-media experience , but then I loved Lisztomania. I love *Turandot* and knowing the libretto so well may be why I don't find this segment the travesty that Tug-3 did.
The Buck Henry/ Rigoletto segment is probably the most approachable for the average viewer -- they are likely to recognize the tunes, and its a classic bedroom farce. I like bedroom farces, so the silliness didn't upset me.
The "Liebestod" segment is so outstanding that I recommend people watch this for that piece alone. "Depuis la Jour" was, for me, beautifully spiritual. And the Caruso recording of "Vesti la Giubba" (aka I Pagliacci) with John Hurt as the clown was wonderful. But people just wanting naked women may feel there is too much music and not enough bare flesh and sex.
