This review will be a long one.

Keitaro once made a promise to a girl when he was younger that he would meet the girl again at Tokyo University; however Keitaro has failed the entrance exam twice and is struggling financially so he calls his Grandmother to try and stay at the Hinata Apartments; what his Grandmother failed to mention was that the Apartments are now a girl's dormitory, needless to say his first impression ends in severe pain but it gets weirder when Keitaro becomes Dorm Manager much to the residents dismay. Over time, Keitaro gets on better with the girls if he can manage to avoid hair trigger violence particularly from Naru who is aiming for the same goal as Keitaro; curious by the similar ambitions, Keitaro wonders if Naru could be the promised girl but standing in their way are rivals, curses and Naru's severe insecurities.
The anime is garbage, the anime only characters are dreadful, the episode plots make no sense, the dub acting is shit, the regular cast act out of character coming across as mean spirited and the animation is cheap and lifeless.
But I really want to give Love Hina a fair chance because the Manga is so much better for writing.
Since character writing is essential in a franchise like this, I'm going to go in depth.
Keitaro: Starts off clueless but once he has a career he can focus on, he actually matures to the point where he is in a better moral light compared to the girls.
Naru: So it makes it ironic that the girl were supposed to cheer for essentially becomes the worst character as her insecurities make her the worst possible tsundere, this plays well into the plot when Naru finally cracks and confesses.
Mutsumi: Only thanks to Mutsumi that Naru was even on that path to begin with as quite often she's more intelligent than her ditzy, sickly demeanour let on. She even fakes amnesia and threatens to marry Keitaro to push Naru into accepting her feelings for Keitaro.
Kaolla Su: Not to say other characters don't have their place as Kaolla Su being so far away from home attaches herself to other people like a little sister, this is evident when her mature side awakens revealing a girl who is very homesick.
Shinobu: Being the opposite, Shinobu closes herself off not helped by a difficult family life leaving her shy and quick to runaway, ironically Nyamo seems to be Shinobu with Kaolla's backstory.
Motoko: Motoko, who is easily my favourite character, idolized her older sister but felt that her sister's marriage took her away from the sword arts and judges men as evil as a result but learns through brutal lessons that she doesn't have to abandon being a woman for the sake of the sword and that Keitaro is a better man than she thought.
Kanako: Kanako pines on the memories of happiness spent with her brother but finds it hard to accept that other women are into Keitaro.
Haruka: Initially lets the chaos go over her head but when Seta pines for her love, Haruka is torn by the idea that she won Seta by default with her friend and Sara's mother passing away, it also suits Seta's need to find a suitable mother figure for Sara who seems to do as she pleases.
Kitsune: Happy to go along for the ride as it's fun to watch, it makes her friend happy and it's always crucial to have an audience surrogate in a harem.
Just by going through the cast properly you can tell that the writing is way better than the shit we ended up with for the anime adaption.
Final Verdict: Simple, read the Manga and Love Hina will actually be decent. The anime was a mistake.
