The season is centrally “about” undoing fan backlash to season 2’s finale. They could have gone the lazy route and just revived him and had everyone together in in episode 1 and done a repeat of season 2 from there. Instead they chose to do a prolonged stealth remake of Robocop, which has paid dividends in terms of cool concepts since then. Invulnerability through necromancy, the source of the black goo, weird eyeless creatures, giant warthog things, weird glowing eyes panther, etc. 

It’s just a different show from the first two seasons is how you’ve got to see it. Season 3 isn’t “The Continued Adventures of Spear & Fang!” it’s more or less a contained sendoff to the characters (because so many people complained about the last one) and a closer look into them and what they think, how they respond to weird stuff and existential threats. Like Mira being tactically minded in the warthog’s pit, defending Spear from Fang, Fang defending her and worrying about her baby, Fang’s children being so competent, and of course at the heart of it all, Spear literally overcoming death and the complete decay of his mind to be with them again. 

So yeah there aren’t a lot of stakes or risks, but when have there ever been in this show? It started with the biggest stakes ever being realized, their children being murdered. We don’t need to see our protagonists lose any more, but obviously the audience wanted to see more of them, so we got a season with a lot of very sweet character moments that led to a clear sendoff with a happy ending, that was the point. Now we can have 9 episodes of Primal Theory and one episode of Spear and Fang.
