I'm certainly not a seasoned opera-goer. I own a few recordings, the more famous ones such as Freni, Harwood, and Pavarotti in "La Boheme", Sutherland in "Rigoletto", and a hour-long selection from the Solti "Ring" recording. I listen to them with varying regularity, often marveling at their voices and the gorgeous orchestrations (and those full orchestras!). I've only seen one opera live, last seasons "Tosca" at the Met. While it was thrilling to hear the orchestra and singers without any amplification, the entire experience was distancing. Even though I had a pretty good seat and could clearly see everything onstage, it was odd for me, a regular musical theatre-goer who does not speak Italian, French, or German to have to read the synopsis before each act (unless I wanted to read the translation, which I opted out of). I thought the lead was very good, but I'm not experienced enough to judge. All I know is I never got chills the way I do when listening to Nilsson in "Brunnhilde's Immolation".
While "Porgy and Bess" can thrill me regularly, a large part of opera is based on the voice and not the words, which is very odd when coming from the musical theatre world, where words are just as important as the music. While you might think that fans of opera and musical theatre should have some overlap, I think the fact that most operas are in different languages put off the young people who enjoy musicals. I'm not suggesting that operas should be translated, I'm just pointing out a reason why someone like me is put off by seeing operas, even though it might seem to be a natural fit.
Perhaps if my Tosca has enraptured and thrilled me, I would have instantly fallen in love with the opulent art form, but as of now, I still feel on the outside looking in when it comes to opera.
