On the other hand, you really need to hear Das Liebesverbot to understand the depths to which the young Wagner could sink.
Fair point indeed - although I suppose I approach that opera as being a kind of Germanicisation of the
bel canto tradition, fused with a certain amount of Hummel
(BTW, the vocal score - which has been out-of-print for several years - is now availabe to download from IMSLP, although it's a chunky-sized file). As I am fond of pointing out, the young Wagner subsidised his student years working for a music publisher - making the piano-score arrangements of Bellini and Donizetti operas. And at least DAS LIEBESVERBOT is about real people - without any Monty Python knights, dragons, dwarves, etc
Although I have a sneaking regard for the RING operas, TRISTAN etc (I have a cyclic relationship with Wagner's music, with peaks and troughs... currently I am in an ambivalent mood about it, although at other times I listen to nothing else) I still regret that no other German composers of much note (read as "excluding Nikolai and Lortzing") developed the Singspiel or "Romantic" opera into a fully-fledged Romantic form in parallel with Wagner's supernatural fantasy-world. There was a lot which might have been done - RIENZI (my favourite of the Wagner operas) failed to bear fruit. Returning to the MEISTERSINGER topic, I suppose it's this element of "interpersonal relationships" - which lies at the heart of the Italian repertoire of the same era - which remains the undeveloped aspect of Wagner's works. When it does (on rare occasion) rise to foreground, it inspires the greatest moments in Wagner's output (second half of VALKYRIE Act III). However, I think most of the reason I can't get on with MEISTERSINGER is that I find Sachs a tedious self-opinionated misanthrope, who would be the Pub Bore in works written by anyone except RW. Pass those same character traits to Verdi - and he makes the same chap into Dr Caius
