Shingeki no Kyojin Season 3 Part 2
The second half is a bit worse, but overall it's great. 9/10.
Kono Oto Tomare!
Surprisingly good, 8/10.
Isekai Quartet
Made me want to watch Youjo Senki and even rewatch Zero, 7/10.
One Punch Man 2nd Season
Except for a couple of funny scenes with the strongest superhero, there was nothing to watch. 4/10.
Bokutachi wa Benkyou ga Dekinai
A mediocre clone of Quintessential Quintuplets, the main cast is supposedly more interesting, but in the end, I liked it less, 5/10.
Kimetsu no Yaiba
A typical shonen, nothing remarkable, but I'm not dropping it yet.
Carole & Tuesday
1/10.
Kenja no Mago
There were some interesting moments, but overall it's dull, 4/10.
Mayonaka no Occult Koumuin
Dropped.
Nande Koko ni Sensei ga!?
The same thing throughout all the episodes + censorship, 3/10.
Kono Yo no Hate de Koi wo Utau Shoujo YU-NO
Seems watchable, I'm not dropping it yet, although I sometimes feel like it.
Strike Witches: 501 Butai Hasshin Shimasu!
7/10.
Choukadou Girl 1/6
The idea is cool + there were a few interesting moments, but it's just nothing special, 4/10.
Nobunaga-sensei no Osanazuma
Fun + great opening, but it could have been better, 6/10.
Hitoribocchi no Marumaru Seikatsu
Dropped.
Senryuu Shoujo
Dropped.
Sewayaki Kitsune no Senko-san

Midara na Ao-chan wa Benkyou ga Dekinai
Dropped.
RobiHachi
Dropped.
Yatogame-chan Kansatsu Nikki
Dropped.

Dropped.
Fairy Gone
Dropped.
Joshikausei
Dropped.
Bakumatsu: Crisis
Dropped.
Shoumetsu Toshi
Dropped.
In general, what I've learned from this season is that if you're watching ongoing series, you shouldn't take a break for more than a week or two, otherwise you risk losing all interest in what you started. After playing Warcraft for the last few weeks, I just didn't feel like finishing half of what I started.
