I agree with you hubee...I loved it (but that's coming from a HUGE LaChiusa fan).
My one criticism of the show is that if you don't know the story, it may be easy to get lost. I read the book this summer and was able to follow the story line easily. I don't think that others were able to.
The criticism about plot focus and length I disagree with. The 4 hours flew by for me as well, and I found many moments in the score that were amazing.
If you're able to focus on different themes (as you must do in almost any epic) then I think you'll like Giant. It deals with many issues, Texas as a place with its sense of independent culture and heritage, an outsider learning to live in a different culture, the subjegation of Mexicans in Texas history, race relations, changing cultural values between generations, the rise of big oil, who gets to define the history of a people/land, death, family businesses and generational expectations (inheritance), interacial relationships/marriage, and the fantasy of a "perfect" father/son relationship.
That is a lot to take in, but I think they are all equally important pieces of the overall story. It's a truly American story. And I think LaChiusa has found a truely American sound for this show. Lush love ballads, Mexican influences, country-western twang, jazzy styles for the younger generation, political march/anthem sounds, blues, and operatic anthems and laments which demonstrate the love of the land and the pain of grief and loss which other cultures (Mexican in this instance) have no problem expressing and reveling in as opposed to American stoicism.
Beautiful music. An epic plot. A WONDERFUL cast (especially Blazer, Cleale, and Robinson). Beautiful and probing lyrics. For example:
I'm lost in her woods/and the light from the moon is her/it blinds and it stings/but it's soft and sings/like a dragonfly's wings/and I'm hunted by her eyes/I'm haunted by her voice
Your Texas/I don't have any interest in your Texas.../Your country...
What's that thing/What's that thing that you can't help but recognize/As clear as the shape of his nose or lips/Or color of his eyes/That thing you know right away/That thing that makes you say/That's my son/That's my son
Just a few examples of lyrics I can remember.
This show isn't for everyone, but if you are someone who can focus on a myriad of themes and connect them, it will be a rewarding experience.
From the evil she done Lord
Set her free, Set her free, Set me free
Don't let my sorrow
Make evil of me
