There's something fascinating about how Japanese concepts don't always translate neatly into English. When it comes to '安直,' I'd probably reach for 'superficial' or 'oversimplified' depending on the context.
I remember watching an anime where a character dismissed complex emotions with a lazy solution - that's when 'superficial' would fit perfectly. But when a game mechanic promises easy wins without depth, 'oversimplified' captures that cheap feeling better. The nuance lies in whether it's about lacking depth ('superficial') or avoiding necessary complexity ('oversimplified').
English lacks that single perfect equivalent, which makes translation such an art form.
