In Secret boasts vigor and thematic richness, that feeling of artists expressing something vital.

There’s never any doubt that this will end badly for the lovers. But just in case, Jessica Lange as the fire-breathing mother-in-law seals the deal.

The Playlist by Kevin Jagernauth

Therese is almost voyeuristically distant from what's happening on screen, asking the audience to observe, but leaving just enough a gap of being completely engaged, that while everything is very well articulated, the impact is more academic than sensual.

A genuine “bodice ripper” of a thriller, with the requisite heavy breathing that comes after said bodice is ripped. The sex isn’t explicit, but Olsen and Isaac suggest the heat that gives this doomed affair its momentum.

Time Out by Joshua Rothkopf

Jessica Lange, as rare as a unicorn these days, seizes on the role of a grieving mother with two taloned hands. If there are any tremors of shame to be felt here, they emanate from her.

The Hollywood Reporter by John DeFore

In a showy adaptation by first-time helmer Charlie Stratton, the story is more glum than seductive -- offering surprising sexual encounters, yes, but too little of the slow burn and psychological depth that might have made the Les Mis-meets-Jim Thompson concept get under one's skin.

The generic title In Secret is as uninspired as the movie itself.

Variety by Dennis Harvey

Serviceable but uninspired, this latest version of Emile Zola’s much-adapted 1867 novel “Therese Raquin” sends its characters to their doom on schedule without stirring much sense of tragedy or emotional involvement.

Slant Magazine by David Lee Dallas

A broad, crude mutilation of Emile Zola's noirish romance Thérèse Raquin that prioritizes heavy petting over plot.

IndieWire

It takes a special talent to turn the romantic lyricism of Zola and turn it into chick-lit.
