If you haven't seen the first season of USA's

Mr. Robot

and want to experience last summer's most surprising show for yourself, you might want to stop reading now and go to Amazon Prime, where all 10 episodes are available. When you return, we can struggle together with What It All Meant and talk about the new season.

It says a lot about the kind of show Mr. Robot is that its creator, Sam Esmail, would like to see a spoiler alert on everything written about it, into perpetuity, and that, space permitting, I don't mind.

If you're still here, you know, or are willing to know, that the title character, played by Christian Slater, is the long-dead father of Elliot Alderson (Rami Malek), the wide-eyed, disturbed computer hacker who's the show's extraordinarily unreliable narrator.

Being dead, or merely deranged, hasn't so far robbed Slater and Malek of screen time, and they're both very much in evidence as Mr. Robot returns for its second season at 10 p.m. Wednesday, as enigmatic and intriguing as ever, with a two-episode premiere to be shown with limited interruptions.

Immediately following that is the premiere of a live after-show, Hacking Mr. Robot, to be anchored by Friends Central grad and former Grantland TV critic Andy Greenwald, who, after-shows being all the rage, most recently cohosted HBO's Game of Thrones talk show, After the Thrones.

Beyond last season's big reveal involving Slater's character, it's remarkably easy not to spoil viewers' experience of Mr. Robot. Because, honestly, there are very few specifics from the second season's first two episodes that I'm sure enough of to repeat.

It's that kind of show.

Summer might not be your season for a dramatic puzzle, but if you're not into trying to fill in the dark edges, it's OK to let the whole thing wash over you, secure in the knowledge that you won't end the night any less sure of what you saw than Elliot is.

An invitation into the mind of a gifted young computer programmer who suffers from social anxiety disorder, depression, and delusions - and who self-medicates with morphine - Mr. Robot also captures the anger and frustration so many feel for a financial system that's rigged against them.

And, if only fictionally, it channels that anger into action.

Esmail, who graduated from Gloucester County's Washington Township High School in 1995, is directing all 12 episodes this season, which opens with the economy in free fall after a cyberattack. Elliot is in self-imposed seclusion, programming his days in a deadly dull loop apparently meant to keep the characters in his head at bay.

How many live only in his head and how many also exist in the real world? You tell me.

Along with the narrator on the CW's Jane the Virgin, Malek delivers one of TV's two best voice-overs, even if we can't entirely trust what he says, and his observations about the people he has chosen to spend his days with are often drily hilarious.

Outside the loop, exciting things are happening (or so I choose to believe). We, at least, have not seen the last of Elliot's sister Darlene (Carly Chaikin), Angela (Portia Doubleday), or the terrifying Tyrell Wellick (Martin Wallstrom), and if you've ever dreamed of a "smart house," you really don't want to miss what a nightmare they can be made into with the rearrangement of some ones and zeroes.

Sure, it's strange watching things happen and not knowing which of them are real, but if Elliot can hack it, surely we can, too.
