I would hardly call Lippa's version lazy...
It's hard to say. I think it's astonishing that these two musicals are based on the same source material and came out within, what, four months of each other and are two COMPLETELY different and exciting interpretations. Each is beautiful in it's own right, and it's (as mentioned above) a matter of taste, and what about a musical really attracts and interests the viewer/listener.
I did not have the priviledge to see either live. Personally, I am more prone to listening to the Lippa version. People argue that LaChiusa's is more intricate and true to the period. Fine. But LaChiusa's IMO does not capture the reckless abandon and ruthless nature that I personally found to be vital to March's poem. Alas, perhaps seeing the two shows would change my opinion. I'll never know. But I would be interested in how many posters are giving fledgling opinions having just heard the respective cast recordings.
