In a sentenceThe bully from 1984 opens a dojo in a strip mall and turns out to have been the interesting one all along

The San Fernando Valley, more than thirty years after the All Valley tournament of 1984. Johnny Lawrence (William Zabka), who lost that final, is a handyman living alone, drinking and getting sacked. When his teenage neighbour Miguel Diaz (Xolo Maridueña) is beaten up in a car park, Johnny fights the bullies off, and Miguel asks to be taught. Johnny reopens the Cobra Kai dojo in a strip-mall unit, old rules intact: strike first, strike hard, no mercy. Across town, Daniel LaRusso (Ralph Macchio), who won that final, runs car dealerships with his wife Amanda (Courtney Henggeler) and daughter Samantha (Mary Mouser). When he sees the Cobra Kai sign lit again, he cannot leave it alone. Johnny’s estranged son Robby (Tanner Buchanan) takes a job at LaRusso’s dealership.

Fi1m review

Six seasons of what happened to the bully from The Karate Kid. William Zabka makes Johnny Lawrence funny and then, without warning, sad, and the series is worth two seasons of anyone’s time. After that it repeats itself.

In 1984, in The Karate Kid, a blond boy lost the All Valley tournament to a crane kick and was never heard from again. Josh Heald, Jon Hurwitz and Hayden Schlossberg have spent six seasons and 65 episodes wondering what became of him. Their answer is that Johnny Lawrence has been in the San Fernando Valley the whole time, drinking, getting fired and not getting over it. Cobra Kai is warmer, funnier and better acted than a sequel to a 1984 teen film has any business being, and it goes on for about three seasons longer than it should. We can recommend it, with that caveat written large.

William Zabka carries it. He plays Johnny as a man who stopped taking in new information around 1985: he drives a Pontiac Firebird, does not know what the internet is for and speaks to teenagers the way his own sensei spoke to him, which is the problem in one sentence. Zabka never winks at us. We laughed at Johnny for the first two episodes and then, watching him stand in his empty dojo trying to teach one nervous boy to punch, we found we minded what happened to him, which we had not expected to.

The nervous boy is Miguel Diaz, and Xolo Maridueña plays him with a decency that makes the arrangement work: he wants a father and Johnny has misplaced a son. Ralph Macchio, meanwhile, plays Daniel LaRusso as a car dealer who gives away a bonsai with every purchase. The show’s best joke is that it is no longer sure Daniel is the hero, and neither is Daniel. Courtney Henggeler, as his wife Amanda, is the one adult in the Valley who can see how ridiculous all of this is, and she gets the driest lines and lands them.

The young cast is stronger than the writing gives it room to be. Tanner Buchanan’s Robby Keene, Johnny’s abandoned son, drifts towards Daniel’s dealership for reasons the first season handles with some care. Mary Mouser’s Samantha LaRusso, Peyton List’s Tory Nichols and Jacob Bertrand’s Hawk are all playing teenagers whose lives are decided by which dojo they belong to this week, and they sell it more often than they should be able to.

It is made cleanly. Paul Varrieur shoots the Valley in flat, hard sunlight, all tan stucco and car parks, so the dojo looks like what it is, a unit in a strip mall with a cobra painted on the window. Ryan Berg gives Daniel’s showroom glass, chrome and potted trees, and Johnny’s flat the furniture of a man who does not expect visitors. The fights are the series’ strongest craft. The editors, Dexter Adriano, Nicholas Monsour, Zack Arnold and Bartholomew Burcham among them, hold wide and let the choreography play, and the school cafeteria brawl in the first season is staged with more clarity than most cinema action. Leo Birenberg and Zach Robinson score it with 1980s synth and electric guitar, played entirely straight, which suits Johnny and nobody else.

The trouble is plot. Every season ends at a tournament. Teenagers switch dojos and allegiances every few episodes, and the grown men behave like the teenagers. Martin Kove’s John Kreese and Thomas Ian Griffith’s Terry Silver both return, and are enjoyable, and the series has to keep inventing reasons for them to stay. By the fifth season we could not have told you which child was training under whom and why, and we noticed we no longer minded. For a series built on rivalry, that is the wrong thing to notice.

The 1984 film taught one lesson and stopped. Cobra Kai teaches it 65 times and keeps finding new students to teach it to. The sixth season, at fifteen episodes, is the longest and is billed as the last, which is right, and about two seasons overdue.

Watch the first two seasons with someone who remembers the crane kick. If you are still watching in the fifth, you will know why, and his name is William Zabka. It carries a 15, and the violence between children is pitched a good deal harder than the films ever were.

Most critics like it, and many are surprised to. The reviews keep returning to the same point: a series spun out of an old film rivalry has no business being this entertaining, and yet it is. The praise clusters on William Zabka, whose Johnny Lawrence is repeatedly called layered and nuanced, and on his pairing with Ralph Macchio, which several critics see as the show’s real engine. The fight choreography is admired, and the later seasons draw some of the warmest notices, with the final episodes described as a satisfying send-off.

The reservations are about writing rather than performance. Coincidence, soap-opera plotting and predictable teen drama come up often, as do uneven comedy and flat dialogue. The spread is wide, and partly a matter of which season is under review. The Guardian finds the whole enterprise anachronistic and unrewarding, and Empire calls the opening stretch of the final season tired and repetitive, watchable only as comfort television.

Straight answers AI written, from our review

Is Cobra Kai worth watching?
Cobra Kai is worth watching for its first two seasons, and we scored it 70. William Zabka makes Johnny Lawrence funny and then unexpectedly sad, and the fights are staged with more clarity than most cinema action. After that the series repeats itself, ending every season at a tournament, and by the fifth we had stopped caring who was training under whom.
How long is Cobra Kai, and what is it rated?
Cobra Kai is rated TV-14 by the MPA in the US. It is an action & adventure and drama series.
Where can I watch Cobra Kai in the US?
Cobra Kai is streaming on Netflix in the US. Availability is checked daily; the links above go straight to each service.
How violent or frightening is Cobra Kai, and is it suitable for children?
Cobra Kai carries a UK 15 certificate, and the violence between teenagers is pitched a good deal harder than the films ever were. There is little to frighten anyone, but the fights are frequent and hit properly, including a school cafeteria brawl in the first season. It suits older teenagers and adults; we would keep younger children away.
What should I watch after Cobra Kai?
After Cobra Kai, try The Karate Kid (1984, Fi1m 81): The original, and still the reason any of this exists; see it first. Then Creed (2015, Fi1m 85): Another old fighter teaching a young one, and Stallone has never been quieter; and Warrior (2011, Fi1m 80): Two estranged brothers in a cage fighting tournament; grim, sincere and well fought.
