This used to be one of my favorite series on TV. Collected all seasons. Even with all the cast changes it hasn't been terrible. But in the past few years, they've taken to killing off all secondary characters that I've cared for. So, humor hasn't been as good, character development has been lacking. And worse, no sign of any backfill of anything approaching a character on a par with what they have killed off.
Not going to cite examples, as that would be giving things away for those who haven't seen the episodes.
Plot has been lacking or just "WTF are they thinking?!?". One non-spoiler, there's a Winnebago, and everyone, I mean EVERYONE from the office is out there looking for something. Which leads to the whole cast once again trying to man handle the winnebago. So, the director of NCIS is trying to push a truck?
Characters behaving out of "character" again, not (to me) adding to the plot at all.
I'd say rewatch the early seasons, skip this one.
