I just don't get the "it's pretentious" argument. It's a sweet, simple, sentimental old-fashioned story about a girl with an over-protective mother who falls in love in Italy. What's pretentious about that? There's nothing "arty" about its structure or content.
The score is all lush old school romanticism which is, if anything, a throwback to a style of writing common in musical theatre and opera decades ago. While some of the harmonics Guettel employs are occasionally modernist in influence, it's a good deal less "difficult" than some of what Weill, Blitzstein et al were writing for the musical theatre back in the 30s. Has basic music appreciation and education regressed so much in the past 70 years that anything more complicated than Mel Brooks' score for "The Producers" is automatically labeled "pretentious?"
I don't know. I actually did walk out of the theatre humming "Dividing Day" and "Let's Walk" and "Say It Somehow" and the title song. These are complicated melodies? They sound very simple and melodic and beautiful to my ear -- although I do have a bit of a music background.
But I find it interesting that my parents, upon hearing a few clips of the score that I sent them are now, based on the music alone, dying to see the show. Neither has ANY musical training of any kind. My mother said that she thought it was some of the most beautiful music she'd heard from Broadway in many years and that it reminded her of shows she used to see back in the 50s. She's not saying that because she's pretentious or elitist -- in fact she doesn't care for most of the "new composers" -- just the opposite. She loves the strings and the beautiful voices and loved the movie and book so she likes the story too.
She doesn't know one thing about music theory or harmonics or anything like that -- she's responding to an old-fashioned type of musical theatre sound that nobody writes anymore and she misses (her favorites are shows like SOUTH PACIFIC, MOST HAPPY FELLA, SHOWBOAT, KISS ME KATE etc...). She hates most of the rock-influenced musicals of the past few decades and all the screaming people do on stage. PIAZZA for her is MUCH more her speed (and I've heard from other friends that their parents had the same reaction).
So see, rather than PIAZZA taking musical theatre in the wrong direction as you argue, perhaps it has the power to attract back some of these older, veteran theatregoers who have been turned off by the overloud (to them) shows like MAMMA MIA and WICKED and RENT and want more "traditional" string-laden, old-fashioned, legit-sung musicals that populated Broadway once upon a time.
There will probably never again be a time with LOTS of shows like PIAZZA on the boards, mainly because not a lot of composers are interested in writing pure romantic music anymore (most are writing song parodies and simple little ditties). But I'm not sure why when one does show up on Broadway (albeit as a limited run at a not-for-profit theatre) it gets dismissed as "pretentious" or "arty." For some, it's a modern day equivalent to the kind of music Rodgers and Bernstein and Loesser and Loewe used to write that's now gone out of style and some audiences miss that and are happy to support it.
