It could be argued that showing up and sticking the landing are the two most important things, and everything in between is less memorable. Line of Duty, one of the most acclaimed and popular detective series of all time (and the most popular in modern UK history), certainly showed up, hooking a sizable audience from the start. That audience grew over six seasons, but was left befuddled by what many consider to be the show’s limp, anticlimactic finale in 2021. Any mention of Line of Duty has included that disappointing caveat ever since. Now, that’s all set to change.
