Charlie’s Angels throws a lot of energy into its fight scenes, but that’s not what gives the movie a spark. It’s Stewart as the comedic relief Sabina and Balinska as her cold, intimidating colleague Jane. Audiences are used to seeing Stewart play the latter, but here she’s extremely physical and funny, screaming like a wild monkey to distract guards during a complicated hacking mission. After telling Elena about how she became an Angel—she moved in and out of institutions because of behavioral issues—gravely serious, Jane reminds her that she grew up on Park Avenue. “More money, more problems,” Stewart says seriously. Since spending her post-Twilight days in heady, gloomy indie films like Personal Shopper and Certain Women, Stewart looks like she’s having fun in every scene, as do her co-stars, and it’s reason enough to see this reboot if you’re a fan of her work.

Despite the pressure for nearly any comedy starring more than one woman to be a revolutionary, cinematic document, Charlie’s Angels is cool with being a little stupid. When Balinska and Stewart, glamorously suited up and serious in disco attire to infiltrate a Brock Industries party, confront an intimidating-looking locked safe, Stewart takes a deep breathe and proceeds to knock out the combination while yelling “bleep bloop bleep bloop.” It’s a silly move, but it lands. Little moments, like an argument about what actor is most authentically Batman (“Is he?” Banks asks incredulously, after someone suggests Ben Affleck, and they’ve all wasted several minutes discussing this) occurring in the middle of an intense planning meeting following a near-fatal mission, honor the best part of rebooting a franchise like Charlie’s Angels: making fun of spy films and the hyper-complicated, deeply serious bravado that accompanies them.

There’s the sense that Charlie’s Angels is skimming the surface of its comedic potential, especially with Banks directing. There’s a better movie buried in here somewhere, if the actors were allowed to loosen up and have more fun rather than roll headfirst into a heavy chase scene or exotic global location. But just to watch Stewart play a goofball for an hour or so, Charlie’s Angels is worth it.

Charlie’s Angels is in theaters tomorrow, November 15.
