I didnt read the manga so for me every episode is a nail biter. This season has the best balance of story and villain of the week type thing. I also think it's the best overall. It worked out that I could binge watch the first few seasons but once it got to this point I'm on a weekly schedule and I'm loving it.
I need to finish season 4! I think I'm in the middle or so. I've started to re-Watch the entire thing with a friend but we didnt get further then ep4 of season 1 sadly. i dont get to see her often so it's staling.
