It's funny, because something else I don't like is dance - if I'm watching, ahem, Britain's Got Talent (which genuinely is a rare event) I simply pick up a book or start browsing YouTube when dance troupes come on. Never got it. So West Side Story is something that I know I ought to watch but it's a long way down a decent-sized list of priorities. I know the La La La America song, of course. More osmosis. Tom Waits also did Somewhere on his Blue Valetines album, so I know that one too. But anytime I see that clip of all the tough guys lining up to dance I just don't get it. Too much Raymond Chandler and not enough Fred Astaire, in my formative years I guess.
Dance, musicals, operas, ballet, classical choral works, Strictly... all areas that leave me cold, and I actually see this as a good thing. There's more than enough "material" out there to keep me listening / watching / reading and learning in just the narrow areas of interest I hold. I mean, I'm not sure I'll ever listen to all the Beatles / Bob Dylan / Miles Davis albums properly in this short life time. I doubt I'll see all the movies I want to see. I know I won't read all the books I long to read. And I'm positive there are not enough hours in the day to practice the guitar enough to get to where I want to be.
I do get the value of cross-fertilisation, and I love to know as much as I can about popular culture and history and the great achievements of writers, song-writers, movie-makers, architects, generals, inventors, cave-painters, etc etc, but there is just too much stuff to address properly and assimilate in a lifetime.
It's not hate, it's just if one has an hour a day to spend on this stuff why would you not spend it on things that move and interest you as opposed to leaving you cold? Especially when you've only just scratched the surface of the top 1% of the stuff you know you'll like.
