Like c.f. Julian, who has the most motive out of anybody and no personality at all. Or Robert, who spent the first two episodes crying and being pants-shittingly scary by turns, but has never stopped talking about protecting the family no matter what. Or Edward, who is supposedly the most dangerous person -- and serves to question Joanna's presence, of course -- yet has negative motive for the murder itself, but whose backstory and portrayal make him wonderful:
Robert: "Edward! I was just going to invite you to the driving range..."
Edward: "Am I a murderer? Did I kill Kimberly Yaeger?"
Robert: "What a silly question!"
Edward: "Is it, though?"
Robert: "What on earth, Edward. Where's this coming from."
Edward: "Haverstock. He's threatening Lyritrol, so I visited him, and he told me I raped and strangled a girl."
Robert: "I wouldn't worry about it."
Edward: "Okay but Dad. Like, why not just answer the question?"
Robert: "I don't have time for this. Those balls won't whack themselves."
It goes on, I'm not even really exaggerating how blatantly Robert refuses to answer this very basic, life-foundation question. Can you imagine? I can't, because it's ludicrous, but it's so weird to think about. Like he's doing the "time" either way, but then really he isn't, it's just media scrutiny and everybody thinking he's crazy so then did he get away with it? Or maybe he didn't do it at all and this is just a many-layered onion of WTF that he has to deal with and never know for sure. I mean, if you were an actor playing this part how would you go about understanding this man, you know?
"I made a bad situation go away so that you could become who you are. Don't let one vicious comment from a man with his own agenda destroy that, I'm begging you. I'll handle Dwight Haverstock. Don't you worry. Don't you worry about anything."
Julian, cooking: "[Names all of the foods he can think of. It's a long list; it takes a while.]
Joanna: "Are all of these foods you're naming part of this meal? Or are you just stuck in a loop or..."
Will: "Man, I hate it when people name foods. That is the most obnoxious fucking thing. I think I wrote that in my blog one time, rather than just coming up with it now to have something to bitch about."
Gabe: "Maybe. Maybe you did. You know what's weird? This strange homeless FBI person that just came into our van has evidence that Will's timeline doesn't work out."
