My thoughts on what I've watched this season in rough order of highest to lowest quality:
Oregairu season 2: I've thought of this show as the more serious counterpart to Haganai. Haganai is a comedy about wacky people who don't have friends for whatever reason in a club together, while Oregairu is a drama/comedy about a guy who's pretty much never had friends being forced into a club in an attempt to cure his bitter and cynical world view, but his way of doing things tends to bite him in the ass.
Kekkai Sensen/Blood Blockade Battlefront: has a nice setting and atmosphere with a lot of fun hi-jinks and a colorful cast of characters. Really the only problem I have is that the chaotic nature of the show can make it hard to keep up with what's going on for some.
Ore Monogatari: a shoujo where the main character who somewhat resembles a gorilla and actually develops the relationship within the first few episodes instead of dragging out them getting together or involving stupid love triangle misunderstanding melodrama like most shoujo do from what I've heard. The main character is really fun to watch and the romance is cute even if the girl's voice is kinda grating.
Arslan Senki: it's still in the prologue stages right now and is thus a little slow, but the source material is a manga adaptation by the creator of FMA of a novel series by the guy who wrote Legend of the Galactic Heroes (one of, if not the most highly critically regarded anime out there) so even if the studio messes things up a bit, it should still turn out pretty good.
Hibike Euphonium: Generally Kyoto Animation productions come to mind as just moe, this one actually has some character drama and seems to be actually going somewhere. Plus the visuals are really great.
Plastic Memories: basically moe blade runner, but not nearly as fun as it sounds. Young adults working at a company that retrieves androids from their families before their limit runs out with one of the main characters being an android whose time limit is coming soon who has to deal with knowing the exact end of her lifespan sounds good, but it's been pretty disappointing. When they retired a little girl android they actually got me to care when things like Ano Hana and Clannad have failed to do so, so I thought it had some serious potential, despite the weird tonal whiplash with the comedic moments. However the next two eps were mostly lame romcom hijinks, the ep after that was a step back in the right direction, but when the latest episode tried to be darker and more serious it had some major plot-holes that have basically ruined my ability to take this show seriously. How did an elementary schooler on foot manage to follow our main characters who were driving into an area restricted by mercenaries? Why are these androids allowed the capability of super strength when they go crazy and attack people if they aren't retrieved before their time runs out? PM might recover, but I doubt it so far.
Shokugeki no Souma: basically a shounen about cooking that causes silly food orgasms drawn by a former "adult" artist. It has some somewhat entertaining side characters and is decent overall, but there's nothing good about it to make it more than just decent. I'd like it more if the silly food orgasms were more common and more ridiculous.
Punchline: Shitty so far, but I fully expect it to become a glorious trainwreck later on. It's a dumb ecchi comedy so far, but the script writer is the guy who did Virtue's Last Reward, 999, Ever17, etc, and there's a character actually dying next episode. The show has a lot of elements like the mc being a spirit separate from his body which is inhabited by a mystery stranger who will cause an asteroid to destroy the earth if he sees panties twice in quick succession and the ability to turn back time to avoid this, one of the girls in his apartment complex being an orange juice themed superhero, an evil organization who wants to destroy the world, some random dude trying to be a super sentai, a baby bear that is somehow important, and an android. Should definitely be entertaining to see where this goes.
Ninja Slayer: Basically it's a less funny Inferno Cop .
Mikagura School Suite: dumb comedy where a perverted lesbian goes to a school where clubs determine superpowers which are used to fight other clubs to get higher ranked and thus better accommodations. Might be entertaining to some, but it's not very good and you're not missing anything so far.
Yamada and the Seven witches: the first episode was an okay romcom about a delinquent who ends up with the ability to switch bodies with whomever he kisses and the potential love interest is voiced by Hayami Saori. However it's a harem and six other girls are going to be introduced so nope.jpg
Is it Wrong to Pick Up Girls in a Dungeon/DanMachi: This show is just so painfully mediocre. It features a fantasy setting with a MMO-style leveling system and boring super special Gary Stu self-insert main character with little personality besides being nice who somehow attracts many girls, including a short and childish-acting goddess with big boobs being held up by a ribbon. He also has a broken power that lets him get much stronger much faster when he has some goal he really wants, which in this instance is to get stronger to get some other girl to like him. It isn't like offensively bad, but it's really incompetent and is the type of thing that people only like because 15 year old boys like escapist power fantasies about being super amazing.
Gunsling Stratos: It's just poorly written all around and isn't even fun to watch.
Owari no Seraph/Seraph of the End: It's basically Attack On Titan x Blue Exorcist, but worse than both of those and with vampires. It's inept at like everything. The main character is a brash idiot who has an edgy past who gets chastised for being so revenge-driven, but basically gets rewarded for his reckless behavior despite the chewing out. The first episode has a virus wipe out everybody over the age of 13 and then vampires take over the world. The MC escapes being used as livestock a few years later at the cost of his foster siblings being killed in an edgy and silly way. As soon as he gets out he's found by people over the age of 13, including a Colonel in the resistance army who looks like he's in his mid 20's because "the prophecy" said he'd be there. Naturally they ignore this prophecy from then on. The next episode then skips ahead another few years and they're making him attend fudging high school to make friends before getting him to attend the special vampire killing class program. The only redeeming aspect is this one girl who is a cheeky smartass voiced by Saori Hayami and is too good to be in a show this garbage.
The Disappearance of Nagato Yuki: Did you like Haruhi? How about instead of adapting more of it, we give you a spinoff in a universe like that of the movie, but with an uglier art style, Kyon has none of his personality, Yuki is a stupid moeblob, and Haruhi doesn't even show up for a few episode from what I've been told. Even then it's probably not much and is more about the Kyon x Yuki romcom. It's as boring as it sounds.
Denpa Kyoushi: It's GTO with an otaku instead of a delinquent, but not funny at all and is pretty ugly to look at.
Triage X: It's incredibly edgy and stupid. Maybe you can wait for the uncensored version to come out if you only care about seeing boobs.
