I'm looking for a word to describe a podcast I was listening to. The podcast was interesting, but contents weren't relevant to my life or objectives, it was just an interesting story that you might recount later at a dinner party, but not something that you would ponder at night time. The second part of the podcast was relevant, and I'm looking for something to contrast this.
What I've got is:
This Radio Lab podcast talks about liars and self deception. It starts off [platonically] enough, talking about everday lying and pathological liars. The final part of it is where it gets interesting – self deception.
Words I've consider are platonic, neutral. Platonic actually seems pretty reasonable here - it's usually used to contrast with romantic, but I think it can be used metaphorically here.
