I agree with you about PIAZZA. It should have won the Tony. (My second choice is DRS.)
However, while you state that SPAMALOT is based on previously created characters and story lines, with music thrown in -- so is PIAZZA. It is based on a novel. Someone else created these terrific characters and storyline -- not Adam Guettel and his co-creators.
It's odd that the four best musical Tony nominees were all based on something else, and that, while they're all strong (and all enjoyable), not one of them -- with the possible exception of SPELLING BEE -- was made up out of the blue. (The SPELLING BEE writers used the documentary "Spellbound" and other materials when creating that show -- but at least created new characters.) Unfortunately, I felt SPELLING BEE was the weakest of the four nominees -- due chiefly to its score.
Last year, with AVENUE Q winning the Tony, I was thrilled that a completely original show took the prize. It wasn't based on any previous story lines or characters. Granted, there was a hint of "Sesame Street," (as in this year with SPELLING BEE hinting of "Spellbound") but it was completely original from start to finish, unlike WICKED that was based on the novel. (And to be honest, the book for the musical was a lot better than the novel.)
Let's hope that next year we get some "original" creations! Wouldn't it be nice to have dual categories for writing, like they do on the Oscars? "Best Adapted Musical" and "Best Original Musical"? If only we had enough shows in NY to be able to fill the nominations in two categories? We can dream, can't we?
Itty Bitty Geisha?
Toyland?
