1. Near the end of the Battle of Hoth, an AT-AT pauses, pivots to the left and almost casually shoots a snowspeeder down. I just love the animation of the walker in that shot.
2. Luke's charge on the retreating Vader late in their fight in RotJ. The wide tracking shot, the choir and musical use of the lightsabers is amazing. Which brings us to...
3. Parallels between the duels in TESB and RotJ. In each, the fighters start out calm, but calculating and looking for an advantage. Then one of them just gets pissed off and starts swinging wildly until the other fellow is backed against the wall and drops his weapon with finality.
4. The asteroid chase. Potatoes, tumbling bodies and more evidence that TIE pilot training doesn't include a warning against flying in tight formation through narrow enclosed spaces.
5. On Endor, when Leia gets shot and felt up in the space of three seconds.
