visually striking... yes i'd admit the Pod Race was. aurally striking too
only thing in AOTC i can think of are the viewpoints from within the clone shuttles when you see other ships blowing up and going down (usually with a live actor somewhere in the shot)
i've always liked the opening of ROTS, at least before Hayden & Ewan begin bantering back and forth. that opening scene kinda put the battle in ROTJ to shame. of course the impact of this battle is completely lost when they get back to Coruscant and it's business as usual.
