I've had an interesting relationship with Sunday.
I tried to watch the DVD 3 times, and proceeded to fall asleep each time. I guess I have to attribute that to the material plus the fact it was on DVD, because when I saw it live I couldn't imagine that it once completely bored me.
Anyway, then I took a Sondheim class, and once I saw how carefully planned the music is, and how the theme of the creation of art can apply to any art form, particularly theatre, I really grew to love it, and only loved it more after seeing it live a couple of times.
The end of the first act always gets me as well -- but it's the music, after he says "harmony," the music is non-dissonant for the first time all show, and when the entire cast starts that beautiful harmonious note, I just cry. The way that the score comes together of its little pieces, like the painting comes together of its little pieces.
Then the fact that "Putting It Together" is actually the same song as "Finishing the Hat" but talking about two completely different things works great as well.
Put me in the camp that enjoys act 2. It brings some sort of resolve to George & Dot, "we do not belong together becomes we've always belonged together," and having the character struggle with these things brings across the mention of "Move On" -- and you also need to see some character change, as Act One George pretty much stays the same.
And I agree, I also always cried when everyone bowed to him.
So I went from thinking it was terribly boring but now I love it. I'm glad I was able to, and had the opportunity to see it at 54.
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
