But now the New York Metropolitan Opera is presenting live matinees through the magic of HD and your local AMC (and other) theaters. They're every couple of weeks, on the west coast at 10 a.m. on Saturday morning. There's a reprise two weeks later on Wednesday evening at 6:30 p.m. You can google all the info: Metopera.org or fathomevents.org.
If you're a senior, $20 will get you the full opera, live, on a huge screen, with subtitles, plus interviews before each opera and during each intermission. You don't even have to dress up (although people do). It's a super way to learn about this art, and presented this way it's very viewer-friendly.
