Some fans attributed the problems with Kate’s character to the “Criminal Minds” writers. Reddit user cool_banana_split wrote “The sarcastic jokes they wrote for this character were so bad, I cringe every time. Don’t think she was the worst but overall just didn’t care for her, I wish Alex Blake would’ve stayed on for longer.” User fjall_persia thought the issue might be due to a contrast in acting styles: “I like Jennifer Love Hewitt on 911, but I don’t think her acting style is suitable for CM which puts me off Kate Callahan.”
It’s true that new characters introduced to long-running dramatic series like “Criminal Minds” do take time to find their footing, particularly as the writers flesh out the character and work out what makes them tick as part of the larger ensemble. Over the course of the 10th season, we came to know Kate, her husband Chris, and their niece Meg as she worked to balance her home life and her commitment to the BAU. It was revealed during the season that Kate had lost her sister Lizzie and her brother-in-law Joe during the September 11 attack on the Pentagon and were raising their niece as best they could. The family dynamic and the approach of the birth of her baby with Chris were avenues for potential new stories that went unexplored.
