Louise is by and far my favorite. Not even close. Gene is second and Tina is last. I don't thin Gene is a bad character. He's just such a ****-up that it drives me mad. Like his thing with the black garlic. I wanted to throw him in baboon furnace after he mushed it up against his fat chest.
Tina: “Gene, I don’t want to say you screw everything up, but maybe Louise does?â€
Louise: "YOU SCREW EVERYTHING UP!"
I think that episode did a good job of expanding on the family dynamic. Linda and Tina mean well and want to help Bob, Louise is often apathetic about most things, but can be bribed to help out, and Gene tries to help but often let's his inattentiveness stand in his way.
Which is a necessity, because as that episode showed, when things were finally going Bob's way, he was freaking out.
