Well, the characters seemed very normal and relatable to me, that's relative to your own experiences and tastes though. Surely people that grew up with social media become more aggressive, extrovert and fun? So you not liking it may depend on what you're accostumed to. The need for inmediate excitement and fun is slowly replacing contemplation and insight. I can't relate that much with the main character either, but I like what the other characters show, and what they hide and how they interact.
