Luther isn’t just going to sit back and let a serial killer run wild. That means he’s going to have to bust out of prison and save the day. Meanwhile, DCI Odette Raine (Cynthia Erivo) is also on the case, and she doesn’t appreciate the incarcerated (and soon-to-be-not-incarcerated) Luther butting in on her work. At least at first. But even Odette has to admit Luther is the best at what he does, and that’s all part of the fantasy world this film exists in. Sure, Luther is a wildly corrupt cop! But he’s also a hero, damn it! Which means all his crimes should be forgiven as long as he gets his man.

This isn’t unique to “Luther.” The “corrupt cop who saves the day anyway” is a well-worn trope in police-based stories, but in this era, it feels especially wrong-headed. No matter: I doubt anyone is watching “Luther: The Fallen Sun” for realism or social commentary. They just want to see Idris Elba catch criminals while looking very handsome, and on that front, “The Fallen Sun” delivers. It also delivers on darkness and a bleak atmosphere that will be oppressive to anyone unfamiliar with the series.

Elba is his usual dependable self — the man oozes charisma, even when threatening people with violence. And Serkis is clearly having fun playing such a repulsive bad guy; the type of villain we can’t wait to see get his comeuppance. This all results in a sturdy little thriller that runs a little long but mostly gives you what you want. Fans of the show will likely enjoy seeing Elba play this role yet again, but just how many more adventures can Luther have at this point? How many rules can he break and still walk away clean? Perhaps I’m overthinking this. Perhaps none of that matters as long as there are creepy supervillains out there, waiting for John Luther to come take them down.
