The makers had a thought like:

'Hey, how badass would be a trailer look with a lady punching her way through different lives?' "Tight, but what's the story?" 'Am sure we can contrive something'.

They couldn't. The film is disconnected, it fails to create any tone right from the beginning. One doesn't empathize with the protagonist. One doesn't feel the urgency when she's said to be in danger and one doesn't feel thrill when she starts fighting. Leave alone the lackluster 'theory'. I spent a freaking 45 minutes, trying to connect with it, finally gave up on it and felt like I should warn others to save their time.
