The Star Wars movies are more about their fantasy than their violence, but that's not to say that it's not without its moment of pure annihilation. Planets get completely destroyed, ships exploded, basically a lot of people die. It happens in a world with laser swords.
But maybe we should reconsider our hero at the center, who definitely has probably killed more people than most might remember (he did pull the trigger on the proton torpedoes that blew up the Death Star). It's a fun supercut of all his kills, and one should not take Master Skywalker lightly.
