Adolescence has been dominating Netflix's Top 10 since it arrived on the streaming site earlier this month.

The four-part limited series starring Stephen Graham, follows Jamie Miller (Owen Cooper), a 13-year-old boy who is accused of murdering a girl at his school.

It arrived on the streaming site on 13th March and hit 24 million views in its first week. It has now broken a record of 66.3 million viewers within a two-week period, with critics calling it some of the "best TV" they've seen and praising its incredible one-take filming style.

Given the success of the show, fans have been searching for what to watch next, and another Stephen Graham series, The Walk-In, has now entered the streaming site's trending shows.

The true-crime series, which originally aired on ITV in October 2022, sees Stephen Graham play Matthew Collins, a former fascist organisation member-turned-informant who worked to bring down Britain's far right.

"Stephen Graham shines in this explosive state-of-the-world drama. Based on real events, it follows an activist and his advocacy group as they confront an extremist organisation," ITV said of the five-part series.

The show premiered on Netflix in December 2024.

Is The Walk-In based on a true story?

It is.

The real-life Collins previously revealed how the show was given fictionalised content and a different name for the safety of the production team.

"The security was extremely tight, there were even discussions about whether to run a full list of credits naming everyone involved," he told the Guardian in 2022.
