Rebecca Ferguson’s sci-fi smash makes Rotten Tomatoes history with season 3

If you thought most sci-fi shows start flagging by the time season three rolls around, well, Silo has just thrown a spanner in the works. Apple TV's underground dystopian series, starring Rebecca Ferguson, has hit a milestone that very few shows ever manage this late in the game, picking up a tidal wave of praise as it heads into its penultimate stretch. If you bailed out after being underwhelmed by season two, now might be the moment to clamber back on board.

Season 3: A Critical Turnaround

The third season of Silo drops on Apple TV on 3rd July 2026, and to put it bluntly, critics have been queueing up to sing its praises. This is especially surprising, given that season two left some viewers feeling a bit short-changed. According to Germain Lussier over at io9, season three 'takes its time but, ultimately, is just as intriguing, and even more revealing, than that excellent first season.' That's saying something, considering how much season one grabbed everyone.

Dais Johnston at Inverse hasn’t held back either, lauding the series as 'a masterclass in post-apocalyptic sci-fi.' And for those who fancy their reviews with numbers, M.N. Miller from FandomWire slapped on a 9/10, calling it 'a brutal, gritty, post-apocalyptic, populist series that reinvents itself in fascinating ways.' Take that as you will—'reinvents itself' is doing some heavy lifting here, but the main point is: this series keeps shifting and actually gets away with it.

Felipe Rangel from Screen Rant clocked in with an 8/10, noting that season three is 'completely different from the Apple TV sci-fi series' first two seasons, in a good way.'

Apparently, it's not business as usual—expect a decent shake-up. Alberto Carlos over at Espinof gave the season a 4 out of 5, pointing out that, thankfully, some of the structural wobbles from the first two seasons have been sorted this time around. Always nice when a show learns from its mistakes.

If you like your praise unfiltered, Katie Doll from CBR dropped a full-on 10/10, saying the show 'is everything a show of this genre was meant to be.' Tania Hussain of Collider popped in with a 9/10 and called it 'thoughtful, gripping, and beautifully made.' And apparently, the season's build to its big finale isn't one to snooze on—Joonatan Itkonen of Region Free gave it 5/5, calling the last episodes 'some of the most intense and brilliant TV I’ve seen all year.'

'Never been a better time to get on board with this show.'
— Chris Evangelista, Slashfilm (7/10)

Where Silo Stands Right Now (and Who’s Sticking Around)

• The show sits on a perfect 100% Tomatometer score at Rotten Tomatoes (from nine reviews and counting).
• Rebecca Ferguson leads as engineer Juliette, doing her level best in a massive underground silo as humanity clings on in a bleak, post-apocalyptic future.
• The main cast also includes David Oyelowo, Rashida Jones, Common, and Harriet Walter—all familiar faces for anyone sticking with it since season one.
• This is all building toward the series' final act, with season three setting up what Apple is billing as the penultimate chapter.
• Nearly every major critic has given the latest batch a solidly fresh rating—ranging from 7/10 up to a full 10.

For a show about people crammed into a claustrophobic cylinder beneath a ruined world, it’s oddly refreshing to see it defy the usual drop-off and actually improve as it goes.
