So, my thoughts can be summed up perfectly by these guys:
Why are they all so stupid?
Also, DH and I argued for quite awhile about Carl shooting that "boy". I thought Carl did the right thing. The "boy" should have dropped the gun when he was told to - handing someone a gun with your finger still near the trigger is not dropping the gun. That "boy" was there trying to kill Rick's people - yes, he was scared and running - but that doesn't mean he wasn't a threat. (I say "boy" because he seemed like an adult to me, but they kept calling him boy/kid)
All that being said, I do think Rick needs to be a parent and tell Carl to get his act together. Although, once you have to kill your own mother, I'm not sure any amount of parenting will help... As annoying as Carl was in season 2, he might just be the most ineresting character now. <---- my random thoughts.
