Soulless mess of a film. Highly disappointing and unnecessary cash grab. Somehow, even the action is boring and repetitive. I can give forgive lousy writing and dialog if we get incredibly visually striking action scenes (like the second in the series for example) but we have none of that here. Just shaky cam'd robotic fights, devoid of anything really interesting or stylistically pleasing.
I'm genuinely struggling to find the positives here. Don't watch this. Stop making unnecessary sequels Hollywood, please stop.
