I stopped watching when Lena left and I could see where it was heading. It wasn't enjoyable anymore.
But I guess you're right. Everyone has a different saturation point. I honestly don't believe, from what I have read of the actions they are taking, that things will get better. It just seems to me to be more of digging the hole deeper. By the time AMC figures it out or finally wakes up and gets someone else in there, it may be too late.
