The Sunday timeslot fit them for years
Yeah, there biggest problem was not wrapping up the Hetty-storyline when they still had a chance.
I didn't mind the change with Kilbride as he was good, and the actor is/was amazing - but Hetty should have quietly retired instead of going off on an "adventure" for years...
... yes, the minus 4 episodes are very noticable in this season - especially that it made things odd at times... I didn't the personal storytelling challenges, as that still made the show - but things definitely stayed unfinished...
