It's based on a web novel with OP protagonist trope. Some say it's a rip off of Saiki K, but that's least of the problem because this kind of OP protagonist trope has been super common in light/web novel scene for a while now and Saiki K itself was a late comer to that trend.
What makes this 3/10 is very simple -- it's just bad.
The source material was actually fairly entertaining and popular because it was makes a lot over the top reference of real world people, events and memes. In fact, most of source material was kind of joke of what's popular at the time, but somewhat tying that to the overarching plot, which made things interesting.
But the anime is nothing like the source material. Most of meme and reference were cut out (legal reasons?) and these were actually the soul of what made original web novel interesting. After cutting bunch of stuff out, story was then stitched together in a messy way that it makes absolutely no sense. And to make things even worse, around episode 8 or so, it completely diverged from source material and starting making it's own story. You'd think that now you don't have cut out half of source plot, they can write a comprehensible story, right? Nope, it's somehow even worse and make less sense.
Not sure why this became an anime to begin with. If you have cut out half of original story arc for whatever reason, you should just realize it's not a proper source material to make an anime with.
