The plot around the bonkers stunt work is a bit thin, but the stunts themselves fully justify the movie. You can see ever dollar spent and bone broken literally up there on the screen, but it also must be said that these stunts are clinging desperately to the line from believable to unbelievable. And half the time they careen over that line and land in Fast & Furious territory. Unless they find an emotional core to build future episodes, this might be as good as a retro-futuristic spy thriller can get.
