re: Best scene in each Star Wars movie

Episode 1 - Darh Maul lightsaber battle
Episode 2 - Count Dooku lightsaber battle
Episode 3 - Palpatine reveals himeslf as a Sith
Episode 4 - Luke using the force to destroy the Death Star
Episode 5 - When the lights come up in the carbonite freezing chamber and we see Darth Vader's silhouette. This scene to this day still gives me goosebumps.. "The force is with you young Skywalker..but you are not a Jedi yet"
Episode 6 - Vader saving his son
Episode 7 - The introduction of Kylo Ren, or Rey catching the lightsaber, tough call.

Edit- My mistake, my favorite scene from the original Star Wars is the opening scene. When the Star Destroyer flies overhead and feels like its never going to end..
