One of the most fascinating aspects of “Mr. Robot” has been its ability to capture the moment — whether airing its series premiere days after the revelation of a massive breach of United States government computer systems, or postponing its Season 1 finale because of a real-world shooting — despite being made months in advance of the news. So it feels right for the show to seize the pop culture moment as well. Thus, even as Netflix’s 1980s horror homage “Stranger Things” becomes one of the streaming service’s buzziest shows of the year, this week’s episode of “Mr. Robot” opens with a paean to getting high and reliving the fright flicks of your youth.

In the opening flashback scene, set immediately before the events of the first season, Elliot and Darlene celebrate an impromptu family reunion by watching a fictional slasher film called “The Careful Massacre of the Bourgeoisie.” (Luis Buñuel and Tobe Hooper, call your lawyers.) It turns out that movie’s rich-kid-targeting killer wore the moneyman mask eventually embraced by fsociety as its symbol. Sure enough, when Elliot tries on a copy provided to him by his sister as a gag, the monster is unleashed. His posture straightens, his low-energy voice grows raspier and more strident, his Rs harden and his vowels sharpen into the distinctive vocal cadence of the actor Christian Slater. Elliot’s not here anymore — we’re looking at and listening to Mr. Robot.

The transformation’s so striking that I wondered if the two performers’ voices had been digitally blended; I might have thought the actors themselves had been switched, if Mr. Malek’s eyes weren’t so big and bright they could be seen clearly through the eyeholes of the mask. The horror movie orchestral music cue that accompanies the appearance of the “Mr. Robot” logo in the credits completes the uncanny effect.

I reviewed this week’s Mr. Robot for the New York Times. This show has reached Hannibal levels of speaking in a cinematic language of its own devising. Don’t believe anyone who tells you this isn’t a great thing.

Tonight, after over a season of portraying a character with bug-eyed, lock-jawed, pharmaceutical-numbed restraint, Rami Malek cut loose.

To the pseudo-orchestral strains of “Lovely Allen” (a mid-’00s music-blog hit by a band with a name not fit to print), Elliot Alderson goes on a sleep-deprived tear of Adderall-induced optimism and excitement. He’s filmed in fast forward, or with multiple versions of himself walking one behind the other, as if a single body’s not enough to contain his manic good cheer. When he climbs stairs, they light up beneath his feet. When he washes the dishes, the sun gleams off a plate like the sparkle of a cartoon character’s smile. When his pal Leon talks to him about “Seinfeld,” he starts screaming things like “It’s classic George, am I right?” in response. (“I don’t like this, bro,” Leon deadpans in return, a fine and funny moment from the M.C. turned actor Joey Bada$$.)

The freakout concludes at the basketball court as the hacker genius turned paranoid recluse sounds his barbaric yawp: “WOOOOOOOO, SLAAAAAAAM DUNNNKKK!!!” It’s a thing of goofily cathartic beauty …and it’s almost immediately cut off at the knees when he turns to us and his narration says, with weary resignation, “You’re not buying any of this either.”

This week’s episode of “Mr. Robot” takes great pleasure in these moments of unexpected, self-effacing humor. Given that the main rap against the show is its grim tone — as if seriousness and self-seriousness are conterminous phenomena — it’s a useful tool for the series to have in its arsenal. On a surface level, this installment is concerned with some of the bleakest events in the story to date: the discovery of the old-school phone hacker Romero’s corpse by his confederate Mobley, the latter’s increasing conviction that their group has been marked for death by the fearsome organization the Dark Army, Elliot’s desperate attempts to overdose himself out of his Mr. Robot persona’s clutches, his garrulous new pal Ray’s tragic and violent back story. But the writing, the performances, and the filmmaking make it seem like all involved are having the time of their lives, off-camera anyway.

I reviewed last night’s Mr. Robot, which was delightful, for the New York Times.

“Why this mask? It’s a bit silly, isn’t it?” The opening lines of the second season of “Mr. Robot” may emerge from the mouth of corporate creep turned America’s most-wanted missing person Tyrell Wellick, but the man speaks for many of us. Despite having joined forces with the show’s mentally unstable main character Elliot Alderson and his hacker confederacy fsociety, Wellick is not above questioning the group’s corny iconography. The Anonymous-indebted disguises, the snide sobriquet, the “Fight Club” posturing: Is there really a method to this madness, Wellick wonders, or is it all a cheesy cover for adolescent anarchism that won’t change a thing in the long run? That’s the question “Mr. Robot” is apparently trying to answer — and so far, that answer is a surprisingly grim one.

I’ll be covering this season of Mr. Robot for the freaking New York Times, where I made my debut with my review of tonight’s season premiere.
