Why are almost none of the characters in this show likeable 😭

I pretty much only like Charlotte and Addison. I’m sure I’ll like Amelia because I liked her on Grey’s but I’m not that far yet. Dell is on thin ice, I keep going back and forth on him. Same with Pete. I can’t STAND Coop, Sam and Naomi. I don’t have much of an opinion Violet. She’s alright I suppose. I liked Sheldon at first but then after Violet and Pete, he became really immature.
