season 3 was actually a big improvement over seasons 1+2
Just finished watching season 3 and I gotto say, it was probably the best season thus far. Lots of interlinked stories, only one filler episode - great for binge watching. Less humor than in previous seasons, but a lot more action/tension, which I like.
While I liked the humor in the previous seasons, there wasn't enough action/tension for me - the new ratio of humor vs. action/tension is by far better. Having more interlinked episodes also works out well, especially when binge watching.
