missing the days of Weed Jesus
I agree about Michonne being quite dreadful. Isn't she new to acting? She is just way too harsh. I think she is being directed this way, though. She just doesn't have the talent to pull it off.
Michonne is a very intense, brooding character in the comics as well. I'm not a good judge of acting, but I think she stays true to the character (except her flimsy swordsmanship). I guess since they haven't elaborated on her background, people might not get why she's paranoid and mentally unstable by the time she encounters other survivors.
