Prime Video is good at a specific kind of rabbit hole. You open it looking for one slick action series and, ten minutes later, you are choosing between military thrillers, superhero carnage, old-school animation, and a sci-fi wasteland with better jokes than it has any right to possess. That range is useful, but it also means the weak choices are easy to make.
MovieRec's current UK provider snapshot, refreshed on 2026-03-04, lists the shows below on Prime Video in the UK. For the live view, go straight to Prime Video UK on MovieRec.
1. Reacher
The safest starting point if you just want something that moves.
Reacher is blunt in the best way. It gives you a mountain of a lead, a town full of suspicious people, and a plot that knows forward motion matters more than showing off. The action is clean, the humour is dry, and Alan Ritchson understands that the fun is watching competence collide with corruption.
If you want a Prime original that rarely wastes your time, this is the obvious first pick.
2. The Boys
Best if you like your action nasty, funny, and fundamentally unimpressed with hero worship.
There are plenty of superhero shows. Very few are as aggressive about dismantling the fantasy as The Boys. It is violent, cynical, and often ridiculous, but the satire works because the series understands how celebrity, politics, and brand management feed off one another.
It is not subtle, and it is not trying to be. If you want restraint, look elsewhere. If you want spectacle with real bite, this remains one of Prime Video's flagship draws.
3. Fallout
The pick for viewers who want world-building without a lecture.
Game adaptations used to arrive with an apology built in. Fallout is what happens when a show understands the source's tone well enough to stop being nervous about it. It is funny, grim, strange, and confident enough to let the setting do some of the storytelling.
You do not need to know the games. In fact, the show's best trick is how little homework it demands while still feeling rich to people who already know the universe.
4. Invincible
Best if you want superhero action with actual consequences.
At a glance, Invincible looks like a bright coming-of-age animation. Then it reminds you, with extreme clarity, that power leaves damage behind. The action is brutal, but the reason the show works is emotional rather than graphic: it cares about what violence does to relationships.
If you are bored of frictionless hero stories, this is one of the sharpest corrective picks on Prime.
5. Batman: The Animated Series
The default if you want something timeless rather than merely current.
Some action shows age into curiosities. Batman: The Animated Series aged into a standard. The art direction is still gorgeous, the storytelling is lean, and the series understands noir atmosphere better than a lot of expensive live-action television.
It is also one of the cleanest examples of how much personality a supposedly straightforward action-adventure show can have. If you missed it the first time, Prime gives you a chance to fix that.
6. Person of Interest
Best for viewers who like procedural structure with a bigger idea underneath it.
The early episodes can seem like a clever case-of-the-week thriller. Stick with it. What starts as a surveillance procedural gradually expands into a much larger argument about prediction, control, and who gets sacrificed in the name of safety.
It still delivers chases, gunfights, and tactical problem-solving, but the long-game plotting is why people stay loyal to it.
7. Chicago P.D.
The pick if you want relentless comfort viewing with a harder edge.
Not every action binge needs to reinvent television. Chicago P.D. works because it is sturdy. You know roughly what kind of tension you are signing up for, the cases keep arriving, and the ensemble gives the show enough weight that it never feels purely mechanical.
This is the choice for nights when you want a reliable engine, not a grand statement.
8. Supernatural
Best if you want a giant adventure with monster-of-the-week energy.
Few long-running genre shows understand companionship as well as Supernatural. The format is accessible, the horror-action blend keeps things flexible, and even when the mythology becomes very large, the real hook remains the brotherly push and pull at the centre.
It is a long ride, but a friendly one. If you want a series you can live with for a while, this is still a dependable Prime pick.
If You Only Start One
Pick Reacher if you want the clearest all-rounder. Choose Fallout if a strong setting matters as much as the action itself. Go to The Boys if you are specifically hunting for something meaner and more satirical.
For viewers who use Prime as a base but want more animation in the mix, Best Anime on Prime Video Channels UK is the logical companion piece.
