I'd rather they behave in the manner that they do rather than hang out in a bomb shelter for 6 months and chow down on canned goods.
So you would rather risk the lives of your family/friends than hunker down and live off what you have? You would fit right in with the cast.
One scene that jumps to mind is when they are outside of the prison. Why not take your time to kill all of the walkers, rather than rush in, get trapped, nearly die, etc.? It's stupid. Every situation turns into a "HOLY SHIT, WE frickED UP" moment when it was completely unnecessary.
Like I said, I know the show depends on their stupidity for action, but it bothers me.
