Stephen Graham's Netflix drama has officially landed on the streaming site and it's already sparking conversation.

TV critics are calling it "TV perfection" while praising its unique one-shot filming technique, while viewers have been taking to social media to share their views, with many agreeing on the "heartbreaking", "traumatic", yet very "important" themes explored within the four-part series.

While not based one specific true story, the drama follows on from the rise in knife crime in the UK. It begins with one of the most devastating scenes as 13-year-old Jamie Miller, played by newcomer Owen Miller, is accused of murdering his schoolmate, Katie.

Throughout the ordeal, Jamie maintains his innocence and insists that he didn't do it. However, his innocence is called into question once CCTV footage and images are revealed.

Despite this, there is a constant question around whether Jamie actually did commit the crime, with various characters, including a supportive DIY store worker suggesting that the video could have been faked.

So did Jamie kill Katie in Adolescence?

Read on for everything we know.

Yes, Jamie did kill Katie.

The truth behind Katie's murder is confirmed in the last 10 minutes of episode one when detective Luke Bascombe (Ashley Walters) plays a video of Jamie stabbing Katie seven times in a parking lot, after following her around.
