Are there any English-language musicals you like?
You mean movies or plays?
Well, for movies, all the greatER Gene Kelly classics: Cover Girl, The Pirate, An American, Singin'... the Hayworth-Astaire are fine too, the great RKO ones, oh, and all the Busby Berkeley and the Eleanor Powell ones of the 1930s... ah! Seven Brides is a riot! love it too!! all the more because of all that is so wrong in and around it

just like with "The Awful Truth" (not meaning it as a musical, just the frivolousness of making great art out of moral questionability) - Kelly's parallel production,
Brigadoon, obviously, stinks... Blake's "Victor or Victoria", and its theatre version...oh I would immensely loathe "The Sound of Music", were it not for Julie Andrews' great art, and for Eleanor Parker's greatness

... Throroughly Modern Millie...
I'm positive I leave out a lot, even more modern ones, but right now, for some reason

they do not come to my mind... oh, and nobody dares suggest stuff like "La la la land" and crap of the sort... I can appreciate Gosling's talent (evident even in that iconic publicity still), but that's it.
When a musical is done like this, even with Foster shrilling around
Just compare the quality of these two parallel productions:
Oh, and there are the Broadway Bares too

but that may be considered more "ballet"
Are there Spanish musicals?
Until he fell into disfavor Placido Domingo was producing Zarzuelas for LA Opera.
Spanish musicals?

if there is some original production, it is all like an Almodovar film: great story and production values, more or less sloppy script and invariable, unredeemingly crappy performers.
The problem with zarzuelas is that of most opera commonly considered "great" and "canonical": it's XIXth century or even later
Musicals in Spain are commonly Spanish versions of American or anyway foreign ones... actually, the first modern musical originally Spanish, I think, was a Catalan musical called "Mar i Cel", first produced in 1989.
Then obviously, there are local reviews, little musicals and all that, but tthere we enter the negligible genre.
