Britten's opera tends to see things in simpler terms. It portrays an Aschenbach who wants a richer form of sexual fulfillment, and who is hemmed in by the social conventions to which he subscribes. But Visconti's use of the Mahler Adagietto is perfect for what I take to be Aschenbach's sexual desire.

I don't think that anything of any consequence is known a priori: all our knowledge is built up by modifying the lore passed on to us by our ancestors in light of our experiences, and the best a philosopher can do is to learn as much about what has been discovered in various empirical fields, and use it to try to craft an improved synthesis.

We know that he gave Aschenbach Mahler's first name, and also his facial features. So Visconti picks up on something interesting. That led me to think about ways of developing further the Aschenbach-Mahler connection.

The classical allusions and the Platonic disquisitions on beauty are no longer a form of cover, but integral to Aschenbach's complex sexuality. Moreover, the wandering around Venice in pursuit of Tadzio isn't a prelude to some sexual contact for which Aschenbach is yearning.

Finally, this is one way to reconcile the delight in beauty with the bourgeois life. Aschenbach, on one reading, has spent virtually all of his adult life balancing his restrained homosexuality, which is bound together with his sensitivity to beauty and thus with his artistic vocation, against the demands of conventional society.

The variety within Mann's fiction is impressive and fascinating. But Joyce is even more various and many-sided. He begins his career with a wonderful sequence of bleak studies about the ways in which human lives can go awry - in my view, Dubliners is underrated.

I felt I should also contrast Visconti's treatment of the novella - usually damned by Mann fans (who typically respect Britten's more "faithful" adaptation). The Visconti film does many quite wonderful things, although there are good reasons for the condemnation.
