My critique:
Carl had way too many unnecessary close calls this episode. It was a bit unrealistic - the walker in the house basically had him and he still managed to escape for a second time in the same day. Then he feels it's safe to sit on a roof and eat cake?
Rick's starting to annoy me a bit - I don't know if it's the acting or just Rick but yeah! The way he fell off the sofa and tried to make us believe he was a walker was also a bit under-done. Rick's pneumothorax or whatever he had was also extremely noisy and randomly disappeared in some places - it was very distracting and I kept thinking it was a walker!
PurpleRain - NOOOOO Hershel can't be dead D:
In this episode, I really LOVED Michonne. We never really knew much about her but I think I know what they are getting at. Her husband, child and the other guy (brother?/friend?) all 'opted out' by killing themselves when the apocalypse started, and she was told to do the same, hence that dream. She got angry/thought they were no longer human so cut off their arms with her sword. Then, when she saw that note in the shop saying "do what I couldn't", it reminded her of what happened which is why she said "I'm still here, you were wrong".
Anyway, this episode was a bit better overall! Loved seeing Michonne's softer personality though - she was so mysterious before!
