The first time we see Jedi in slasher mode is in Return of the Jedi. Then again in The Phantom Menace. How many battle droids ended on the blades of the Jedi? The hallway scenes of Vader and Luke just fit in with this.
Frankly, if you don’t like them just because other fans do, that is pretty silly. You should like or dislike things for how you feel about them, not because of what other people feel. These two scenes are popular because they show how powerful the father and son are and how formidible one Jedi can be. Something that was shown over and over in the Clone Wars and the PT.
