Premiering on CBS on September 22, 2005, Criminal Minds ran for 324 episodes over 15 seasons, wrapping up its run in February with a 2 hour finale.  16 different agents served with the BAU over that time, with Matthew Gray Gubler’s Spencer Reid being the only constant for all 15 seasons.  The show somehow also managed to outlast both of its spinoffs.

The show had obviously run its course, but I’m still kind of sad to see it go.  15 years is a long time and I’m not sure there will be much coming to replace it on my schedule.
