I loved the first season of this one exactly for not pretending to be what it is not, but instead running with the tropes that are center stage of the genre. Save the princess, marry the princess, rinse, repeat. Coming from modern Japan to medieval world? Introduce revolutionary technology! Or at least bicycles. The world has special rare magics? Master all of them! Wait, not overpowered enough? Have God on speed dial before you even start. 10/10 would watch again! Well, to be fair, it was also one of my first isekai so I was not too tired of the genre yet.
The second season mixes in a few new things with a lot of "more of the same", and some things may have reached a level of "too much". In particular, the harem grows beyond the point where I could convince myself he genuinely cared about each waifu like I did in season one. There is a mix of new old and tired tropes like create-your-own-country, mecha, secondary harem of robo-girls, more inexplicable waifu overpoweredness-by-association, etc. The novelty of being in a new world is gone now and replaced with routine, and the focus shifts slightly from being on the hero more towards the overarching plot concerning the whole world. About damn time if you ask me, and actually it's not enough. We'll have to wait for a third season, just let's hope it doesn't take another 6 years again.
I still rate this high because of subjective feelings, like the fond (even if by now vague) memories of season one. I do see its drawbacks more clearly too, but... if you want an isekai, you have to face the music. You have to accept the drawbacks. You have to want the drawbacks! If you want an isekai, you got the grandfather of all isekai right here.
