Regardless, I was definitely a fan of one scene in particular.
Watchmen - The Times, They Are a-Changin'
Whatever failings that the entire movie might have, one thing Watchmen does properly is the intro sequence. It perfectly chronicles the rise and inevitable fall of the eponymous costumed vigilantes.
It's crisp and cinematically nice to look at. Plus it has a great Bob Dylan song (though the lyrics could seem a little on the nose, I happen to think it avoids it - your mileage may vary, of course).
