Not exactly binged, as I tend to get bored with most TV shows if I watch more than two or three episodes in one sitting, but I've just finished watching season 3 of Gotham. Excellent ending to an excellent season. I have to admit, I did lose interest during season 2, but stuck with it, and they've improved the series no end.
I know it's been shown, but I've included spoiler tags as the scene I talked about was such a nice surprise, I don't want to ruin it for those who haven't seen the episode.
