Ballerina has the bones of something stylish, but the final product feels like it’s been patched together—and to be fair, it was. You can see the reshoots and delays in the seams. Ana de Armas gives it her all and carries the thing with poise, but the action’s mostly samey, and Gabriel Byrne’s accent is anyone’s guess. Keanu and Anjelica Huston are in and out far too quickly. It’s watchable, just not particularly memorable.
