It took me a while to start watching season 10. I was very sad Sid, Bunty, and Mrs. M weren't going to be part of the season at all.
Thankfully, adding these new characters also shook up the Father Brown formula. I thought that was really wonderful. If it had stayed the way it was, the loss of those beloved characters would've overshadowed the season.
I laughed more this season than any other. I really enjoyed this infatuation between Mrs. Devine and Inspector Sullivan.
Brenda is wonderful. This character adds so much depth to the show, and Mrs. Devine adds a lighthearted sense of adventure in ways we haven't seen in previous seasons.
I liked how different things were this season. I rewatched all of Father Brown before I got to season 10. I thought it was fresh, interesting, and just delightful.
