For the same reason, the intro to Episode III. The fadeout from the title crawl to the war drums to the epic space battle. I LOVE that shit, so underrated.
Visually, you cannot beat the Darth/Luke battle scene in the carbonite freezing chamber in ESB.. it is like art. The orange and the blue are so beautiful
From Mando: the part in The Tragedy when Fett goes absolutely fucking HAM on the bucketheads as they’re trying to advance at the base of the mountain (this is the one scene that got me super stoked for the Boba Fett series)
Unironically, "you were my brother, Anakin. I loved you" though I suppose it is more of just a line rather than a whole scene. Ewan was too good for those films.
The opening scene. Lots of movies had featured spaceships like the one we initially see fleeing. When it reveals the size of the star destroyer, we know that it's going to be a new type of story.
I love that they show Leia's ship coming in from the bottom of the frame, so we're above it, but then the star destroyer from the top, so we see it from below. Really ups the intimidation factor and ensures we know who we're rooting from before anyone has even spoke a word.
In The Phantom Menace, the entire podrace scene. Yes, it's goofy as heck, but man does George Lucas know how to make some pure campy exciting fun.
In A New Hope, the trench runs. God, they're just SO COOL, especially on a big screen.
In The Force Awakens, Han being rescued by the Resistance, from the time Han Solo is captured to the time Leia shows up, is a masterclass example of editing and music.
Binary Sunset. Luke staring pensively out into the distance as he considers his place in the universe and where it may or may not go. I’d be staggered to find anyone who can’t relate to that.
The finality of Rogue One, Order 66, Luke looking into the double sunset, and Luke choosing to not kill his father after defeating him even though the emperor wants him to.
The trench run, and specifically the sequence of Luke being left as last man standing when Biggs is killed, then "Use the force, Luke," "You may fire when ready,", "I have you now," and "You're all clear kid, now let's blow this thing and go home," BOOOOOM!!!
Death of Maul in Rebels. After years of searching for his self imposed rival desiring the revenge for all the years of pain he had endured he finds a withered old man who had moved on. Obi-Wan rises to meet his once mortal enemy baiting him with the starting form that his master had used all those years ago. Maul takes the bait and is cut down by the man he had hated for most of his life. In his dying moments he is held and reassured by the same man that the Force, the only thing that Maul had left would be at balance once again. It's lasts seconds but it's like a painting in motion with how much is going on
Seen lots of things mentioned already, but I found the absolute power of the Death Star destruction in Rogue One amazing. The Jedha destruction scene is scary like an atom bomb.
The power in the swings of Vader is just pure rage. Smashing Luke's lightsaber, slashing the walls, he's pissed now. Luke should have been easy to beat in his eyes but he's still fighting him.
