The anime's satire and chuunibyou aspect that so many reviews talks about is almost non existent. The little satire that exists, is there just to try and make the complete lack of a story line something ''funny'' since its ''satire'', the ''chuunibyou'' is a excuse from the author to feel free to lick the MC balls at every chance he gets.
Seriously, its tiring to see everything revolves around the MC being ''the most badass, smart, powerful, cool'', to make it worse he is boring, its like the image a 12 year old has of a cool character.
This may have been the most downside of the show for me: The Harem
The Harem was... seriosuly one of the weirdest ones I've ever seen, the ''satire'' bit only made the harem worse, the anime truthfully believes its not a harem isekai - even tought every characters is a cute girl thats on the MC harem, but since this one thinks it is not a harem, it does not care about making girls have personalities, managing the amount of girls on the harem and their feeling, etc. making this the worst Isekai Harem there is. By not admiting it is a isekai harem, its harem gets worse than isekai smartphone for example
the author actually had the ability to write 2 male characters both of which made the MC seems like a real person and do some funny stuff, so I thought there was some hope, but no, they were cast aside, making this a true isekai harem.
To give the anime some point tought, there are some ''good moments'' that might be enough to keep you watching, moments that give characters personality or dept, these are cool, I almost gave a 6 raking because of them, but sadly they are treated almost as non canon, sometimes being completely forgotten about or some ''added dept'' is removed/forgot to show of how ''fucking cool'' the MC is for the 16° time in a row.
In short, the anime explores and thrives on the self-insert aspect, specifically on the self-insert aspect for 14 year olds who never touched a woman and think they're dumb enough to fall in love with anything, plus you have to think ''dark+powerfull = badass'' to not cringe trough the anime
