First Review Of 'Divergent' Hits... From 'Divergent' Author Veronica Roth

Veronica Roth gives the movie based on her book a big thumbs-up.

A critical consensus on the "Divergent" movie won't be in until later this month, and we mere mortals won't be able to see it ourselves until the film hits theaters. (Boo, hiss, sob.) But if you're excited about the film, here's your cue to get excited-er, because author Veronica Roth has gotten an early peek at the movie based on her work.

And according to her, it's awesome.

In a post on her Tumblr, Roth announced that she'd flown to LA for a special advance screening of "Divergent" — and was thrilled to discover that her book had been turned into a "beautifully shot" and "suspenseful" film, with the futuristic, broken-down Chicago of her imagination rendered in all its bleak and gritty glory.

"Chicago is such a gorgeous city," Roth wrote, "and to see it transformed into this futuristic wasteland was incredibly cool."

The author also had her own transformative experience as a viewer, when she got so caught up in the drama of what she was seeing onscreen that she kind of forgot she had written it. Roth wrote, "Even though I am so familiar with this story, I clearly remember grabbing the arms of my chair when Tris runs to catch the train after the Choosing Ceremony because I was nervous that she wouldn't make it."

And while Roth wasn't about to give away every last little thing about the film, she did take a moment to let fans know that the heroic Tris and brooding Four will not disappoint when we see them brought to life by Shailene Woodley and Theo James.

"If I start calling people out specifically I'm just going to gush about everyone," Roth explained, "But since Tris is very much the anchor of the series, and Four is of particular interest to many of you, I feel like I should say that Shailene Woodley as Tris and Theo James as Four are everything I hoped for (or maybe more than I dared to hope for)."

And since Roth didn't elaborate upon what she meant by "more than I dared to hope for," we'll just assume until further notice that the movie includes a three-minute montage of Theo James flexing his thigh muscles in super-slow-motion.

"Divergent" will release nationwide on March 21.
