The most insidious factor plaguing "7 Seeds" is the constant, wildly unrealistic string of minor, plot-advancing events. Falling 20+ meters onto a pile of rocks and not being harmed at all, killing tiger-like beasts with a rock and a stick, bursting into fire after lightly touching the flame of a lighter... Normally in an anime, if an unexplainable event happens a single time, it can be overlooked as a momentary lapse in the writer's judgement. When it happens multiple times an episode and is instrumental to the progression of the central plotline, the show becomes a joke.
Perhaps even worse than the ridiculous string of unrealistic events are the characters' backgrounds and dispositions, which make the story impossible to enjoy. The organizers of the 7 Seeds program were so wildly incompetent that they somehow managed to send multiple serial-killers, rapists, and sadists to repopulate the Earth. As if that weren't enough, they MADE some of the kids into these monsters before sending them off. How is it possible to be so terrible at your job that you are incapable of simply selecting a decent and competent human being?
The production quality is of course also atrocious. There are a handful of nice scenic views scattered about, but for the most part, it is obvious that this anime was created by Gonzo. When is the last time they managed to make something that actually looks good? Maybe the Afro Samurai sequel in 2009? It is amazing they're still making anime at all, if "7 Seeds" is the best that they're capable of.
The reason this anime might deserve a 3/10 rather than a 2/10 or 1/10 is because it does have some redeeming qualities. A small amount of the characters are actually respectable, decent human beings who are capable of challenging the unknown in daring and inspirational ways. Also, deciding to keep the focus moving between such a large cast of main characters was ambitious, with a lot of potential upside. Unfortunately, the idiotic decisions routinely made by many of the characters and the repulsively sadistic tendencies of some of the other characters (who are supposed to be upstanding citizens from good families) make the show impossible to properly enjoy.
Although I have yet to watch the second part, I would not recommend this show to anyone, under any circumstances. If you want to watch something terrible for comical appeal, go watch "King's Game" or "Ex-Arm". Those shows are at least bad enough to be funny. If you instead want to watch what "7 Seeds" tried in vain to be, then a couple good contenders are "Btooom!" and "Dr. Stone". Just don't watch "7 Seeds", unless you want to be regretting it for days.
