Colson Whitehead’s prize-winning novel becomes an expansive miniseries.

The last thing you want in a TV show portraying slavery is phony sensitivity.

Don’t let that all-encompassing historical monstrosity off the hook with a chilly, inoffensive lecture.

So credit directorBarry Jenkinsfor turning upThe Underground Railroad’s heat.

In a terrifying 19th century located halfway between myth and your newsfeed, the whip cracks sound like gunshots.

Magic-hour light shines so bright on enslaved men and women that their bodies are outlined with halos.

There are flashbacks, flash-forwards, and a font so huge that “Georgia” splits across two lines.

Outkast, the Pharcyde, andMichael Jacksonplay over end credits.

The anachronism is light, but telling: A white man references FUBU more than a century early.

Her plantation is the hell-world setting for the first chapter, which depicts atmospheric violence with bloody authenticity.

Jenkins draws you into the circumscribed life on the plantation, filming the surrounding nature with a tormenting beauty.

The trees are part of the cage.

And a white man’s arrival is an occasion of elemental horror, silencing all conversation and music.

Yet there are notes of trippy satire.

The Southern gentry are sociopathic dandies, enjoying a courtly dance while they burn a screaming man to death.

Cora’s fellow captive Caesar (Aaron Pierre) plans an escape.

Their journey leads into a quest through various ruinations of Black life.

That glossy refuge has a paranoid underbelly, with an eerie medical twist.

Other characters beyond Cora and Caesar step into the spotlight.

Whitehead’s novelwas a phenomenon, and Jenkins is fresh off Oscar seasons forMoonlightandIf Beale Street Could Talk.

So there’s a no-expense-spared quality toRailroad’s epic sweep.

Mbedu brings power and pain to a part that requires endless hours of fear.

Jenkins excels at a dreamy state of intimacy, but the allegorical setting can turn distancing.

Here, vivid characters keep getting trapped in abstract themespace.

And the 320-page book has become a semi-shapeless streamer, with most episodes clocking over an hour.

I like Edgerton, but the character calls for more internal chaos than his trademark perturbation allows.

The instinct is magnification, a zeroing-in on key plot moments and characters.
