My Best Friend, His Girlfriend and Me turns a simple love triangle into an all out family feud, and Netflix has delivered a comedy that argues loyalty and romance cannot always share the same house. The German film follows two lifelong friends whose bond gets tested the moment a new woman enters their apartment and their lives. Marco Petry directs this tale of stunted adulthood, jealousy, and the messy price of growing up. What unfolds is far bumpier than the trailer promises.

While the pair once split everything evenly, one new arrival is about to test how far friendship can stretch before it snaps.

Olli, played by Kostja Ullmann, never had friends of his own until Matze, played by David Kross, walked into his life and stayed. "Inseparable" barely covers it, since the two even worked at facing desks inside the same real estate office. A long-planned year of travel around the world was supposed to be their next big adventure together. Rebecca, played by Janina Uhse, arrives and Matze falls fast, throwing that entire plan into question.

Rebecca does not simply date Matze; she moves into the apartment Olli and Matze already share, turning close quarters into a daily standoff. She questions the year abroad from the start, worried it will pull her boyfriend away right when their relationship begins. Olli sees a stranger rearranging a life he spent years building beside his closest friend. Neither side backs down, and the apartment quickly becomes cramped in more ways than one.

The setup borrows a familiar shape, a jealous best friend guarding turf against a new partner who refuses to be pushed aside. What separates this version is how quickly small irritations curdle into open hostility between two grown adults. Marco Petry frames the rivalry as comedy, yet the pettiness on display feels closer to sibling squabbling than romantic tension. By the time the pranks begin, the audience already senses this will not stay lighthearted for long.

While the opening act plays the rivalry for laughs, the film soon proves that neither Olli nor Rebecca intends to fight fair.

Matters escalate quickly once Olli and Rebecca stop pretending to tolerate each other and start plotting instead. Teeth get dyed, a toaster catches fire, and the pranks arrive one after another without much creativity behind them. Olli, aided by their more settled friend Schmitti, played by Ferdinand Hofer, works to push Rebecca out of the picture entirely. Rebecca refuses to be an easy target and answers every move with one of her own.

The trouble is that neither character earns much sympathy across these exchanges, leaving little reason to root for either outcome. Olli behaves exactly like the man-child he is repeatedly accused of being, unwilling to let his oldest friendship evolve. Rebecca, meanwhile, comes across as controlling in ways the film never fully questions or challenges. Watching two unlikable people battle over the same person makes the middle stretch feel more exhausting than entertaining.

Nobody in the story pauses long enough to have an honest conversation, which keeps the misunderstandings piling up past the point of believability. Matze mostly stands on the sidelines, reacting instead of resolving anything between the two people who claim to care about him most. The comedy leans on chaos rather than character insight, so laughs come at the expense of connection. Underneath the antics sits a story that never quite decides who it wants viewers to trust.

As the pranks fade, the film shifts toward a bigger question about what growing up actually demands from old friendships.

Beneath the antics, the film reaches for a message about outgrowing old habits and making room for change. It also leans on a shaky idea that friends and partners exist on opposite sides of a line, forcing a choice between them. A side couple, a settled husband and his strict wife, gets held up as proof that giving up freedom equals maturity. The framing feels dated rather than thoughtful, and it undercuts whatever emotional weight the ending reaches for.

Olli eventually recognizes his own selfishness, works to reunite Matze and Rebecca, and lets go of the trip he spent years anticipating. He sells his ticket to Pia, a woman he met by chance, and the two fall for each other while traveling. Matze and Olli reconcile at the airport, proving the friendship survives even though the joint journey does not. The ending wraps things up neatly, perhaps too neatly given how messy everything before it felt.

My Best Friend, His Girlfriend and Me had a genuinely fun premise buried somewhere inside all the yelling and sabotage, and the cast clearly commits to the chaos even when the material does not return the favor. Instead, the film stays mean-spirited for too long and rarely earns the softer moments it reaches for near the end. The dialogue meant to say something about balancing love and loyalty lands flat more often than it lands true. Viewers looking for undemanding comedy might still find something here, though anyone hoping for real depth will likely leave disappointed.
