“Allegiant,” the first of the two-part finale to the “Divergent” trilogy, was the most disappointing film I’ve seen since its predecessor, “Insurgent.”

The movie starts off where “Insurgent” ended — the factions are collapsing, and Tris (Shailene Woodley) and Four (Theo James), along with Tris’ brother, Caleb (Ansel Elgort) and former Dauntless members Christina (Zoe Kravitz) and Peter (Miles Teller), escape over the wall into the outside searching for a way to find peace in Chicago. There they find things that shake their entire worldview, including a mysterious organization that has been experimenting on the population for years.

My list of problems with this film seems endless. First and foremost, the script is weak and features a lot of obvious statements (with some so bad it makes it seem like a caricature of looking into the camera on “The Office”). The exposition was so drawn out that I was anxiously waiting for the movie to end; there’s no doubt that the final book was fractured into two parts solely to make as much money as possible before the trilogy ends (a common theme in the dystopian genre).

Unlike “Divergent,” the plot of “Allegiant” isn’t particularly action-heavy. This isn’t a bad thing — in fact, I’d rather see development of major and minor characters over an explosion — but “Allegiant” replaces this action with random futuristic technology to distract from the lack of substance in the plot. Tris uses “memory tablets” to experience her mother’s memories as she would have seen them, but the scene doesn’t add anything to the overall conflict besides something pretty to look at.

Plot holes run rampant and minor characters are all but forgotten; friendships formed in the earlier movies are ignored in favor of Tris and Four kissing dramatically. No decision is explained and no clear motives are stated, and the main threat really isn’t all that threatening. I spent the entire movie wondering what the point was if I could easily predict how it would end (and I read the book almost three years ago).

Tris wears a lot of white, zip-up vests that make her look maternal and creepy, while Four (and everyone else) wears the same outfit almost the entire time. Every aspect just seemed incredibly unbalanced and unfinished, topped off with a heated speech from Tris near the end about the importance of rebuilding Chicago, whose sentiments didn’t feel sincere. It plays off as trying to be deep instead of actually being revolutionary and moving.

The only redeeming factor is Tris and Four’s solid relationship throughout. There wasn’t a torrid love triangle or a pointless fight, just a loving and caring partnership that didn’t try to take over and allowed them to focus on more important things — I’m looking at you, Katniss. I will say that the acting was well done, especially from Theo James and Ansel Elgort, and any blunders can be blamed on the initially poor script.

I give “Allegiant” a deserved D+. Try harder on “Ascendant,” please. I’d like to see the film adaptations of an excellent book series at least start and finish on a good note.
