My partner and I are drowning in the middle of a Criminal Minds watch-through at the moment. We have been for about two months and I'm sure we have at least six months left. It's not world-class prestige drama, like Breaking Bad or Succession level, but I do find it way more interesting than your standard American police procedural show.
If you're not familiar, it's about a team of FBI profilers - which basically means they use clues from the crime scene to construct a fairly accurate idea of the kind of person that the murderer (the offender is almost always a murderer) might be, which helps them catch the criminal before they can kill again. Performances are strong and the writing is pretty good, although the editing is pretty dated in the early seasons. If you do happen to be looking for a very long show to binge I would recommend it (it's on Disney+).
I would never claim for a second that it's the same quality as a show like Luther but still a good watch that I am more than happy to keep viewing.
