The only season i dont like is three(first two episodes. The episodes are just so deep and serious. It really brings out the human side of Holmes but they were still very hard to watch since lots of things were happening and most of them where bad. Last episode is hood tho. Very emotional
It's funny you say that because despite of the fact that the season 3 is not my favorite (my favorite is the season 2), it's the one I find the funniest ! Particularly the episode 1 and 2, by the way !
