I rated the previous seasons as following:
Season 1: 6
Season 2 and 3: 7
The main reasoning behind this, being that especially season 1, had insanely rushed material, and the plot felt lacking.
Season 4 is a whole different thing, and I am going to explain why.
The plot/story in this season starts off well made, and interesting. I rushed through this season faster then any of the others. I kinda feel that the whole plot and storytelling style grows on you. You kinda realize that this anime was never ment for slow-paced plot with huge details in how the world works (Log Horizon is a grand example of this). It's also not all about the realization of the style, it's about the presentation of the style in this season, that makes it better then the others.
For one of the few times in this anime, I have actually understood most of Louise's actions. I have understood when she got mad at him. (Because, be honest, who didn't hate the guts out of that girl in the first 1-2 seasons? Atleast I did. I was actually so mad at her at times I was hitting my PC.) The example here comes from when Saito kissed someone he shouldn't have. And there was no explaining against it. After all, it's a harem anime, so stuff like this will happen, but I felt that the way Louise and Saito handled it felt rushed and left them both with a weakened relationship. This did not show at all, as their relationship is basically rising every single episode in season 4.
Many people are giving this season a -1 for lackluster episodes. I am mainly thinking about the mid-episodes where Louise, Saito, Tabitha, and last but not least Siesta is at their mansion. These episodes, are episodes I really like. For me, a person who really falls in love with characters, these are golden. I really enjoy just watching the characters enjoy themselves, and I really enjoy watching Saito and Louise getting together. I personally give more positives due to the season having time for relaxed pure good-feel episodes with lots of HILARIOUS harem.
In this season, I believe everything improved. Especially the humour. I was actually laughing quite a lot. If you have already finished the season, I am especially thinking of when Tifa enters the room and can't fit her dress on, Louise goes to help, and her dress just falls off whipping her boobs out. Saito's face really got me.
Not just this, but now that Louise treating Saito as a dog became more rarely, it got humourus when she actually did. And as the season progressed in many ways, I also had the feeling that he deserved it. Not like he did in the first seasons, where in my opinion wished Saito to dump Louise and go away with Siesta.
Siesta is one of the best developed characters in the anime if you ask me. Her personality is so easy to spot and is really amazingly developed in a way that you feel like you really, really know her. She is a very humourus character. I can't count how many times she made me laugh this season, and each laugh made me love her more. This one scene, when Louise and Siesta is talking about what I remember as potentional enemies, and Siesta brings up Tabitha's dragon. When Siesta impersonates the dragon, is the best Siesta moment in my opinion. (If anyone has a YT clip or gif from this, please PM me as I really wanna see this again.)
As it goes for the op song in this season, I have to say I am a bit disappointed. It did not live up to it's previous season 3 op, and of course First kiss from season 1. FIRST KISS KARA HAJIMARU!
The ending was for me, settling. I love endings that leave you fed up (not in a bad way) with the anime. There are no questions to be answered, and everything went as you had hoped. This ending had that, and I loved every second of the last couple of episodes.
As an ending to my review, I thank the developers of this anime for an amazing ride. I am very glad I picked this anime up, and I am very glad I continued watching after a lackluster season 1. This anime and especially season 4, have given me tons of laughs and tears. Tears of sadness and joy from the last episode.
