Mercy review: Chris Pratt's new AI sci-fi thriller is so haphazard, you'll wonder if ChatGPT could do a better job of writing it

TechRadar Verdict

The best way to sum up Mercy is by describing it as a slightly more tolerable version of Ice Cube's War of the Worlds. If you ever dared to watch the latter, you'll know that this is far from a compliment.

Pros

+There isn't a role that Rebecca Ferguson can't make work
+Chris Pratt clearly loves life as an action hero
+A fairly satisfying payoff

Cons

-The armchair-bound effect wears thin very quickly
-We need to collectively agree to stop telling stories through social media
-Feels incredibly cheap
-Kenneth Choi underused
-Somehow uniquely generic
-Struggles to sustain its momentum

I need everyone in the movie industry to listen up and repeat the following pact: "I solemnly swear to never make a film told through the lens of social media ever again. Never will I sit my main character in front of a screen, digesting the rest of the storyline through open internet tabs, Instagram feeds and MacBook files. I will only include digital elements if it effectively serves the plot."

Agreed? Great, because Chris Pratt's new AI sci-fi thriller Mercy is the latest victim of this heinous crime. With a 101 minute runtime, Pratt spends 90 of those sitting in the same chair, wrongly accused of a murder he didn't commit. Instead of being given a defense lawyer like a normal society would, he has to face off against an AI-generated judge in a 'mercy' courtroom (who conveniently looks exactly like Rebecca Ferguson).

If he can't prove his innocence past a certain percentage, he'll be fried on the spot. Override the algorithm sufficiently, and he'll walk free. Cue an entire movie of sifting through ring cam footage, facetiming witnesses and finding crucial evidence on his daughter's private Finsta account.

After about 15 minutes of this, the gimmick wears off pretty quickly. Pratt himself is clearly loving it (possibly due to the ease of his character also being called Chris) but unsurprisingly, this doesn't translate offscreen. Mercy is mundane in its own unique way, but there are few surprises – it'll hit you over the head with its ambivalent AI messaging.

Mercy refuses to call AI a hero or a villain, and that's a missed opportunity

Watch On

"Maybe humans and AI both make mistakes" is a line of dialogue in Mercy that I've only slightly paraphrased, and it sums up the movie's moral vagueness in one nifty sentence. Sure, we've just spent an hour and 40 minutes watching an AI-generated court judge nearly kill Chris over a wrongful conviction, but we all make mistakes, right?

This was Amazon MGM Studios' chance to lay down the AI line by deciding what side of the industry argument they're on. Instead, they've chosen to sit on the fence, and that transforms any vim and vigor Mercy did have into pure monotony. If we're not using storytelling to send home a powerful message, especially about something so ever-changing, then what's the point?

Of course, the point is to make a bit of money at the box office by seeming to touch on a topical subject. It's the same way that a social media influencer might look like they're supporting a social campaign, but are actually doing the surface-level bare minimum to help it. Mercy could have been an industry-changing heavyweight piece of art, but no – let's play around with some CGI graphics instead.
