Season Three of Travelers is on Netflix

... and while I haven't finished it, I believe it is heading towards an all-series conclusion.

 

TL;DW: Travelers is a 10 episode per season Canadian SF show featuring Eric McCormack (the Will from Will & Grace) as FBI agent Grant MacLaren -- sort of: in the first episode, he dies and his body avoids dying because an agent from the future takes over his brain. The agents (Travelers) are being sent back to organize into teams and change the crapsack future that they come from, hopefully into something better.

It's big on relationships, philosophy, and tragic necessity in the service of a hoped-for better future. There is no episode which one could mistake for a random procedural show.

I'm about halfway through the third season now. The first two seasons each end on cliffhangers.
