Watchable if odd and slightly confusing for newbies. For fans, it's a good adaptation of a problematic novel - so good that it suffers from many of the book's flaws.

Rating: 6/10 (19 March 2014)

When beloved books make their way to the silver screen, the resulting movies are usually met with much frustration and rending of clothes from amongst the literary faithful. A character is changed beyond recognition; a crucial plot-point excised; an important theme lost in the murk and swell of a film. Oddly, Divergent isn't actually a bad adaptation. In fact, Neil Burger's film is as good a version of Veronica Roth's wildly patchy source novel as you're likely to get. Whether that makes for a good movie - especially for people who've never read the book - is another matter entirely.
Divergent begins in a post-apocalyptic Chicago divided into five factions, each valuing one virtue - Dauntless (courage), Erudite (wisdom), Candour (honesty), Amity (kindness), and Abnegation (self-sacrifice) - above all others. It's an odd system, perhaps, but one that is apparently necessary to keep chaos at bay. Tris Prior (Shailene Woodley) has been raised in Abnegation but, try as she might, she cannot completely subsume her self or her desires. Indeed, the aptitude test that everyone must take at the age of sixteen suggests that Tris doesn't belong in just one category: she is Divergent, equally at home in three factions.
Come the day of the Choosing Ceremony, she decides to forsake her family to become Dauntless: a decision that plunges her into a nightmare initiation process in which the weakest are summarily kicked out of the faction. As Tris navigates the politics and perils of her chosen world, trying all the while to hide the fact that she's Divergent, she encounters her fair share of allies - Christina (Zoe Kravitz), Will (Ben Lloyd-Hughes) and possibly her charmingly broody instructor Four (Theo James) - and enemies, including the brutal Eric (Jai Courtney) and vicious Peter (Miles Teller).
Anyone unfamiliar with Roth's book might find themselves trying to puzzle through this seemingly shapeless mess of a plot. It ebbs and flows in odd directions, dancing around Tris' desire to be true to herself, before it gets a little lost in the dystopian clutches of Jeanine Matthews (a gleefully icy, evil Kate Winslet), an Erudite leader hellbent on bringing down the entire Abnegation faction. Along the way, Tris literally battles her fears under the influence of a simulation serum, toughens up physically, strikes up a sexy chemistry with Four and frets over her brother Caleb (Ansel Elgort). Within the confines of this universe, it makes an odd kind of narrative sense, but the logic of it all never really bleeds through.
Here's the thing, though: this strange, frequently illogical plotting is very much a defining characteristic of Roth's novel - and, in fact, becomes more of a problem as the trilogy progresses. (Anyone who's read Allegiant, the controversial final novel in the series, will know just how difficult it will be to adapt.) The emotional and logical flaws present in Divergent the film, then, are - for the most part - already inherent in the book. Why does Jeanine, supposedly one of the smartest people in the community, plot and plan the way she does? How does the entire society function in this utterly dysfunctional way? Technically, Burger can't really be faulted for failing to develop a coherence and logic that was never there in the first place.
In fact, Burger actually substantially improves upon the novel in several ways - he keeps the film mostly free of Tris' inner voice, which becomes increasingly moony and silly as her crush on Four grows by the day. Burger plays up a zip-line sequence that highlights the joyful recklessness of the Dauntless, as Tris soars freely through the midnight air. He also handles the problem of Tris' fear landscape very well: instead of simply willing herself out of the influence of the serum (as the Divergent can do), she must figure out how to face each of her fears in a non-Divergent way. These scenes are shot with quick, simple visual flair, dispensing with some of the novel's trickier convolutions.
Of course, Divergent isn't a perfect adaptation either. To Roth's credit, there are some truly dark, painful moments in the novel which transcend its loopy narrative. It's no surprise, and yet it's a little disappointing, that these bits simply vanish from the film, no doubt in the interests of securing a PG-13 rating. As a result, Peter is a far less repulsive antagonist than he is on paper. For instance, he doesn't brutally (and casually) maul a fellow initiate who's doing better than him in the rankings - an incident that's crucial in the development of his character in the subsequent novels.
The young cast works hard and quite well together. Woodley makes for an intriguing screen presence, effectively playing both the steel and softness of Tris' choices. James, heretofore best known for dying in Lady Mary's bed in Downton Abbey, acquits himself reasonably well - he's not as leaden as some of the trailers have suggested, and he forges a believable chemistry with Woodley. Of the supporting players, Teller is the standout, so good in his easy malevolence that he actually makes the thought of Allegiant as a movie quite appealing.
In the final analysis, Divergent is likely to divide audiences. Fans of Roth's books should be, on the whole, pleased. This is a frequently very good, intelligent adaptation of a rather problematic novel. Everyone else, however, might be less enamoured of the final product: a film that, just like the book on which it is based, boasts a compelling story and some great ideas, but is also messily executed, overly complicated and a tad nonsensical.
