I had considered four stars.
1. Really weak action scenes. Mostly just flying kicks & takedowns; heavily dependent on camera angle for itsy bitsy believability. Very mundane, seen before, nothing new.
2. Getting really old. The usual car chase that was laughably mundane, and the machine gun - please! Gawd!
3. Usual prop scenes of showing an expensive sports car; club scenes; fashion.
4. Plot nothing new. The same old corporate selling of dangerous device to baddies. Dangerous device could pass as a child's puzzle toy. Dangerous device fails plausibility & middle school science.
5. Acting & dialogue - sad.
