Harry Potter: Dimensional Wizard by LazySageDao

1) Basically it has so f#cking less action. In around 100 chapters I can say mc only really faught one battle. That Battle was short and okay but It's too little, I get it mc is quite strong and there is not much enemy to fight in Harry Potter world but here it is authors job to do something about it. Mc is getting stronger or is getting proper training but hardly any battle. After 100 chapter there is 1 good fight but the fight itself was bit disappointing but it was a proper fight, but as I said it's not enough.

2) Too much, simply too much research, experiment & especially 'bs knowledge' . Yes, some are quite interesting but most of them are just drag and it's annoying, if it was in limited numbers then this point was not that terrible. I thought that Warlock novel had too much 'studies' and less action but this novel opend my eyes to see, how another author can write that point more badly.

3) This is what really ruined my interest in novel- Terrible romance & Harem. At first mc was bit of a man-whore which was fine, mc admitted he was just playing and it was fine as it was not too much or too serious. But I had hope that author will eventually write proper romance or atleast few such moments.
But.... Hahaha. Author is genius, he completely skipped every damn thing or even a damn notion and straight away added bunch of women in harem out of f#cking nowhere!
Around some 126 chapter, author simply said after a time skip that mc have captured bunch of canon women as his f#cking 'Concubines'- ofcourse. Motherf#cker!

Hermione lol, she was just a child of age 12-13 before time skip and she was like a student of mc who barely was occasionally mentioned, ofcourse never any romance just student-teacher talks. And vola, after time skip, she is one of MC's Concubines.
Fu#k I especially hate the word Concubines, why can't it be just a 2nd, 3rd or something number wife? Concubines are just sex slaves and collectibles of a man. Anyway nevermind that, don't wana nag on that point now lol.
But guess what, Hermione atleast has some screen of her existence before time skip, but what of MC's other Concubines? Haha no they just dropped from sky out of nowhere, like Luna and few others. They were never introduced or talked about since the beginning of novel but suddenly they are 'so lovey dovey' Concubines of mc.
