Shapeless, what do you think is the best way of explaining to people the difference between a musical and an opera without sounding 'snobby' as seems to be the key word people have used here, but whilst still stating that the latter takes more musical ingenuity.
I don't think I can give a neutral opinion since I love almost all opera and hate almost all musicals vehemently. Factually, there is a difference in musical form, harmonic development, eloquence in melodic form. All the usual differences between a music that pays strict attention to the language it uses and on which does not to the same extent. Yet there is still a difference in meaning, too.
I don't know what harmony it is in musicals, but there is always some kind of chord progression which really annoys me, I'll see if I can find an example. Actually, the musical 'Wicked' is full of them. I need to work out what it is exactly.
My main thing is the level of emotion in Opera is something I cannot find in musicals. Having said that I really like the rocky horror picture show, but I suppose that could still be conceived of as 'dramatic.'
My favourite operas at the minute are:
R. Strauss: Elektra

and Salome.

Which I love because I've been unable to find any composer other than Strauss which installs such a high level of emotion in me. The prickly feeling.
Birtwistle's Punch and Judy:

Which I find to be the most fascinating, gaudy, wonderful, horrible, ugly, mentally disturbing thing ever written. This youtube clip doesn't do it justice.
Also, the concept of Glass's Einstein on the Beach is damn cool. Unsure whether I could sit through it though, too static.
Oh god, there's so many more. I could go on forever.
