The author is either deluded or hasn’t watched the series if he believes that Oswald Danes is a character that anyone is rooting for.
Quite frankly, the most disturbing episode they ever had on the show was in Season 1 ... Countrycide. I literally wanted to go burf before it was over, and stopped watching again until this season. I guess it is possible they had more disturbing episodes, (like I said, that stopped me), but I really dont think it is possible to get any darker than that episode.
