If thereâs one genre that never seems to lose its grip on Netflix viewers, itâs true crime.
From jaw-dropping murder mysteries to deep dives into fraud, cults, and cold cases, the streaming giant has built an almost endless library of documentaries that promise shocking twists and late-night âjust one more episodeâ moments.
Whether itâs a slick, cinematic docuseries or a tightly packed feature-length investigation, thereâs always another dark and compelling story waiting in the queue.
With so many gripping titles to choose from, it takes something truly special to stand out from the crowd.
Yet one documentary film has managed to do exactly that, with viewers saying itâs so compelling theyâve watched it not just once, but multiple times.
In a sea of sensational cases and headline-making scandals, this particular story is proving that even seasoned true crime fans can still be completely hooked.

Tell me who I am â 97% on Rotten Tomatoes â and viewers say itâs even more powerful
The true crime doc tells a haunting yet deeply moving story of identity, loss, and painful revelations.
The audienceâs reactions have been overwhelmingly intense, with one calling it âone of the most haunting documentaries Iâve ever seen.â
Another writes: âMy heart is absolutely broke.â
In agreement, a third adds: âAbsolutely heartbreaking.â
âSuch an interesting documentary,â comments a fourth.
Somebody else says: âMy jaw dropped.â
Critics, too, have had much to say about this documentary film.
On Rotten Tomatoes, the doc boasts a 97% approval rating from critics, whoâve praised its compelling narrative and sensitive handling of complex themes.
Tomris Laffly of RogerEbert.com commended director Ed Perkins for treating the story with the respect and care it deserves.
Similarly, The Guardian described the documentary as âslickly pieced together like a psychological thriller,â emphasizing its engaging and emotionally resonant storytelling.
Twin brothers, one hidden truth
The Netflix-produced documentary tells the real-life story of twin brothers Alex and Marcus Lewis.
When Alex loses his memory in a motorcycle accident at the age of 18, he relies on his twin, Marcus, to help him piece his identity back together.

However, Marcus chooses to shield Alex from the horrific truth of their childhood abuse, instead constructing a fabricated past to protect him.
The doc unfolds in three powerful acts, with the first detailing Alexâs struggle to rediscover himself, the second revealing Marcusâ painful dilemma, and the third showcasing an emotionally charged confrontation between the brothers as the full extent of their past is finally laid bare.
The power of brotherhood
One of the most unforgettable moments comes towards the end when Marcus finally tells Alex the entire truth after decades of secrecy.
The sceneâs raw emotion and vulnerability left many viewers in tears.
In an interview with Decider, the brothers opened up about the âincredible giftâ the documentary has been.
âWeâve achieved closure beyond anything I could have imagined with each other by making this movie,â Alex said.
âThatâs an incredible gift the film has given us.â
Both brothers want viewers of the doc to know that they âa very positive outlook on life, despite everything that you see in the movie.â
Alex added: âWeâve both got good marriages, and we both have two children around the same age.
âWe live very fulfilled lives. Weâre busy in our jobs, we run our company together, and we run everything together that we doâalways have.â
For many viewers, itâs this final act that cements Tell Me Who I Am as far more than just another true crime documentary.
What begins as a shocking story of trauma and deception ultimately transforms into something unexpectedly life-affirming â a testament to resilience, forgiveness, and the unbreakable bond between brothers.
By the time the credits roll, the focus shifts from the horrors of the past to the strength it took to survive them.
Itâs that balance of devastation and hope that lingers long after watching, and perhaps explains why so many people feel compelled to revisit the doc again.
