If they went all dallas on this show, I would crap in a box of packing peanuts and send it to the exec director. Stuff like that is just a cop out for having actual storytelling skill.
As far as Rick being inconsistent, I think its just there attemot at cramming 10lbs of character in a 5 lb bag. Like it was said earlier they are trying to add depth, just poorly executing it. I kind of get what they are jabbing at, The group has been through alot of trauma. They spent winter [the lean season], running from place to place trying to live hand to mouth, Rick led them through that. That alone is enough to rattle someones core, running in desperation, hoping for another meager meal. That kind of hunger is maddening, it drives you to a cliff and holds you off of it. Now add to that, his wife cheated on him, and is carrying a child that may not be his.. but his best friends, whom he had to kill. Finally they get to a semi safe place, and he loses his wife, even if they didnt get along he still loved her. Now if all that dosnt rattle your core he now has to raise two children in a world where everyday you could be on the menu. If that dosnt push a man to insanity, I dont want him as my leader, you would have to be a sociopath for it all not to rip you apart. Thats kinda what they are trying to add to his character, this ptsd addled father of two trying to make it in a world gone to hell.
I understand that its hard to write that all into a short tv show, but it could have been executed better.
