Mr. Osomatsu
What's the Story?
MR. OSOMATSU is a comedy anime series about identical sextuplet brothers and their bizarre and mischievous misadventures. From playing as superheroes that harass regular people at a barbecue, to mistakenly working at an illegal sweatshop, and getting kidnaped by famous horror movie villains. These brothers always end up in all sorts of wacky predicaments in their dysfunctional quests to get ahead in life. Their rivalries, clashing personalities, and conflicting goals always end up dragging each other down.
Is It Any Good?
This show has a wacky, over-the-top sense of humor that won't be for everyone. But if you can put up with the gonzo comedy, ridiculous situations, and hard to follow random plots, then there are still some hard laughs to be had from watching Mr. Osomatsu. There really isn't a central plot to follow; the series is episodic with each episode consisting of a few random misadventures. The sextuplets are identical which can be very confusing and jarring because their distinguishing characteristics are very minor. Often, it's hard to tell which character is doing what in the fast-paced episodes, especially in such chaotic environments. Each brother fits a certain role and personality type in the series, they are "normal," "cool," "responsible," "sluggish," "airhead," and "spoiled." All these clashing personalities usually end up sabotaging the brothers' efforts to get ahead in life in comedic fashion. The sextuplets are in their mid-20s and the situations they get themselves into are often very adult so keep in mind that this anime is not for younger audiences.
