In throwing together sensitive beta Stu and the testosterone-fueled Vic, “Stuber” is trying to say something about the hot topic of toxic masculinity (aren’t we all?), but it has its cake and eats it too. Stu might yell at Vic to talk about his feelings or being a better father, and yes, he does call out just how illegal everything Vic does that day, repeatedly. But for every one of these moments, there’s a scene where Stu learns to “man up” by becoming violent himself, shedding his compassion, empathy and respect for human life. At the end of the day, the two men have apparently learned new ways of being men from each other. Vic becomes more sensitive, while Stu embraces his own power. But the half-hearted cultural commentary gets lost in the violent melee. What we see doesn’t match their words.
