I have a friend who told me she’d never seen Star Wars, and at first I thought, “What, you have to see it!” But then I realized, “No, you don’t have to see it.” It’s Star Wars. It’s great, but it ain’t gonna change your life.
So, if you’ve never seen it, TL;DW (Too Long; Didn’t Watch, get it?) has an animated sketch telling you everything you need to know. It’s also enjoyable if you have seen Star Wars.
