One scene (and it only lasts like 2 seconds) is when Yoda is fighting the Emperor in the senate chamber and the camera slowly rotates as the center platform rises above all the empty senater seats with both characters' sabers flying as the music swells.

Now that is a mighty fine scene right there. So much is said in such a small amount of time. You can see that the fight is more than just a battle between two opposing fighters.

Too bad that only 2 seconds of a 170 minute movie are of any poignant quality.
