Kristen Stewart is a good actress, despite what you’ve told yourself. When not in movies containing the word “twilight,” Stewart has proven to be a talented individual who can take on a variety of roles—though admittedly most of those roles involve her biting her bottom lip. In Camp X-Ray, Stewart delivers  a fine performance as a conflicted soldier tasked with guarding prisoners in Guantanamo Bay.

Yes, Guantanamo Bay is still a thing.

There are people being held in Guantanamo Bay who have been imprisoned—sorry, detained—for nearly 15 years, without trial (by calling them “detainees” and not “prisoners,” the United States is not bound by the same statutes of the Geneva Convention). They may be bad people, but they’ve never been proven to be bad in a court of law.

Camp X-Ray is about that dilemma... soldiers are tasked with guarding prisoners who may be terrorists, or may not be. Stewart plays Cole, who quasi-befriends one of the prisoners (Peyman Moaadi, A Separation), an extremely smart and well educated man obsessed with Harry Potter and resigned to the fact his life ended long ago.

The movie is mildly interesting, an opportunity for Stewart and Moaadi to flex their acting muscles in a series of dialogue-driven scenes. Stewart is good, but her character seems to exist primarily for Moaadi to do his thing. Moaadi is excellent and, building from a script by director Peter Sattler, manages to create an intriguing, memorable character.

Camp X-Ray itself is less memorable. While perfectly serviceable, and perhaps even worthwhile, there just isn’t a lot of meat to the movie. That’s strange to say given how good the acting is and how strong many of the scenes are, but Camp X-Ray didn’t instill in me the sensation that this is a movie that means something, even though it has something to say.

It’s a good drama, but just that: good.
