Anime of the Season

Death March- Despite it being a rather abortive attempt to put a great LN/web novel series into anime form, there are some good points to this anime.  The animation itself is good, as is the characterization.  The everyday life parts are first class, and the animation (if not the action itself) in the action scenes is pretty good.  The reason most people don't like it is because the story never goes anywhere and it is a bit too much of a slow life anime.  This is a hazard inherent in making anime out of incredibly long book series, so it isn't surprising in retrospect, but this was about when they began seriously overdoing isekai, so this series became a victim of the excesses of the time.

Grandcrest Senki- Decent action high fantasy anime.  However, it never goes beyond being decent.

Killing Bites- People have genetically-altered humanoids combined with animals fight each other for entertainment.  Generally doesn't go anywhere, though the action is good at times.

Beatless is an example of what NOT to do when making a sci-fi anime.  The AI characters are too alien to be relatable (including the supposed main heroine) and the protagonist is too much of a simpleton.  It makes it impossible to invest emotionally into the story, so the watcher generally isn't interested in the results.

Overlord II is more Overlord.  If you liked the first season, you'll like the second.

Sword Gai- Random sword monster rampages, no real story beyond that.

Saiki Kusuo 2- It's Saiki Kusuo.  If you like the series' humor, you'll love it, if you don't, you'll fall asleep.  I laughed.

Violet Evergarden - I only know that it has female MC who is the former child soldier who has lost both hands, has good drawing courtesy of Kyoani, and it's the last work from Kyoani before a mad man struck the tragedy on them.

Citrus - Well, you're right on it being serious GL. A very serious one, so much that my favorite GL reviewer called out Mei as robot just because the author keep writing her as someone who repressed the emotion very much even with Yuzu did her best to thaw Mei's heart. While to be fair Mei's situation is very messy, the fans definitely find the reservation toward what Mei do to Yuzu in the beginning (Forcefully kiss the latter) with the setting (Yuzu became Mei's step-sister) is definitely didn't help at all to the fans reception. So yeah, Citrus is more or less GL series with full of drama, and it's one of the first work with full GL story adapted as the anime.

Sakura Clear Card - After CLAMP took a massive backlash toward their involvement in controversial Blood C, they decided to go back to their less confusing (And successful) word Cardcaptor Sakura with them making the manga in 2016 before asking Madhouse help to animate it in 2018. While it's quite clear that Madhouse can still make good drawing and the opening song is quite good, I'm not quite sure that it can rival the old series, especially with the Clear Card that resemble the old Clow Card and the mysterious situation behind the new characters. Also yes I know the manga is still ongoing, although I didn't feel like to check the manga to see more of the story.

Darling in the FranXX - It's Evangelion like robot story with the MC are a male and female pair who'll become the couple at the end, and of course they'll face a lot of danger in the series. That said, my attention on this is going to a certain controversial scene in episode 14, which apparently cause very severe reaction among the fans so much that it's rumored the VA got the death threat. Other than that, obviously I didn't watch this in the first place, so whatever.

HugPC - Toei clearly understand the fans didn't like no physical fight in KKPC, so much one of the announcement in HugPC is they'll return the physical fight. From there, Toei keep doing their best to satisfy the fans, to the point it become overdone to me by them add the past team into three episodes, which bear the mention those episodes are important episodes because two cadres are defeated in those three episodes. Thankfully Toei didn't make the cadres defeated by past team in the recent series (HSPC). Anyway, HugPC is about Hana who got the task to defeat the enemy that come from the future who chased the mysterious baby Hugtan. Forgot to mention that Kwamura did the design work for HugPC, so of course my favorite Precure reviewer like it (Alongside the crossover episodes).

Emiya Family Menu - Someone definitely notice on how Nasu like to keep writing about food in good detail, and then made the manga about the food in Shirou's household. The anime staff obviously notice another Fate work to milk, and thus we have this anime. As for what I can say, at least the mangaka wrote about the recipe so the Fate fans can have the same food as Fate characters.

That's all for what I can comment in regard of Winter 2018 anime
