Abe Golfarb makes a reasonably convincing talk-show host confronted by a listener who can predict the beginning events of “End Times” in “First Time Caller,” a deathly-dull thriller severely limited by a lack of visual variety.

Goldfarb, as acerbic chat show host Brett Ziff, smarts-off and insults one and all on his streaming call-in show, “Brett Free…in your heads.” He zings advice to lovelorn Incels and their obsession with “quality women,” ridicules assorted conspiracy nuts and cultists, riffs on Anti-Semitism and punctures pronouns up and down the alphabet.

“Show me someone who’s still ‘non-binary at 50,” he challenges one and all, labeling that a “dorm room fad.”

Insult him back, stick up for an unnamed pop singer in the Taylor Swift mold and “You’re DUN-zo.” Cut-off.

All of which goes out the door when he takes the call from “Leo,” a guy who sounds like he’s “calling from the john,” and not because there’s an echoey quality to Leo’s inane fanboy musings.

Leo occasionally makes a noise like an old man seized up by too-much-cheese. The catch to this constipation is when Leo seizes up, tsunamis happen. And earthquakes. He’s in touch with the menopausal spasms of Planet Earth. He’s predicting the future.

That premise is moderately interesting. We just have to get past how long Brett would have given Leo (voiced by Brian Silliman) to get to some freaking point or other (any talk show host in America would have dumped out of the call within a minute) and find more entertainment value in an hour of visuals of Goldfarb complaining, questioning and grimacing at what he’s hearing, and what he’s confirming by picking up live-streams that go black or video of disasters he can find on the internet.

The film’s modestly-budgeted but not incompetently-made. Some of the talk-show patter is polished.

But the reason your average talk show host is leery of a “First Time Caller” is the risk that they’ll be as unfocused, digression-prone and vocally uninteresting as Leo the Sh–h–se Seer.
