This.
That R1 scene only existed to pander to a part of the SW fanbase that believe they need to see lightsabers flashing around in a story that's not about the Jedi/Sith war at all. It had absolutely nothing to do with the film's story arc, and without it, would have flowed right into Star Wars without missing a beat. In fact, R1 should have used Stormtroopers to attack the Rebels handing off the plans, as they were always making the first strike as seen in the next film (in chronological order), so there would have been consistency of Imperial methods, instead of..lightsaber porn.
Because you don't understand it doesn't make it wrong.
