Meh...
I hate so much Rick's family: Lori is one of the most stupid wife/mother I've ever seen and their child needs to be beaten every day since he's so naughty.
It's sad that my favourite character is gone...
Anyway I agree that this kind of zombies are really "stupid" NOW... In the first episode, when they smelled the horse Rick was riding I remember that they were running very fast.
Now they kill these monsters so easily that I ask what kind of soldiers were in Atlanta.
Still the Sophia/barn episode is the best one IMO.
