Does this forum have a spoiler tag?
Attack On Titan is definitely not overrated imo. I hated one part of the first season (something that happens to the MC that first surprises you like "Wow did they really just do that?" just to move back on it on the next episode, if you do a plottwist then it should have an impact imo) and it has occassionally a slow episode or two, but it has many interesting characters (I love potato girl Sasha) and tons of twists that were all clearly well-planned from the start. But I didn't rate it 10/10 until I watched Season 3 Part 2, that was just perfect execution.
Some people seem to have problems with CGI animation, but I already got used to it when watching Knights of Sidonia. Its story was amazing enough to keep me going and eventually I didn't mind the CGI at all anymore. Ajin I love mainly because of the MC in the manga and the first season of the anime. Too bad the second season didn't follow the manga and was apparently written by someone who had no clue about the personalities of all the characters, so they simply didn't behave consistently anymore.
Shiki was okay, or great even when looking at it objectively, unfortunately I hate that particular subgenre (I think naming it would actually be spoilers). Actually, I just hate fantasy genre including all its creatures in general except in video games. But I admit it's the best series I ever watched of that subgenre.
I think there was a similar horror anime that was called Sheep May Safely Graze or something like that. Unfortunately I can't find it anymore. Maybe it was this one?

Oh, did you watch The Promised Neverland? I think you'd like that one. Though the manga is better.
Yeah.
I actually got to watch all those romance animes lately because 2 months ago I watched Toradora! for the first time (German Dub is new) and it ended up completely breaking me for two weeks because I found the character so relatable that I couldn't bear not seeing them anymore. One of its charms is definitely that the protagonist behaves like a real human rather than according to his "your typical MC" cliché. For example he doesn't tolerate the tsundere abusing him and doesn't go victim mode. It's my favorite anime of all time now.
I see why Clannad was one of the animes suggested to get past the Post Toradora Depression Disorder. The MC definitely has similar qualities and he is generally pretty unique. While he is good hearted and helping everyone just like in all other animes, he also likes to play jokes and really doesn't help anyone who doesn't really need his help (like his best friend). He has so many amazing quotes like:
Girl: "Say something too!"
MC: "Nah, I enjoy just listening."
Or:
Girl: "Do you think that's funny?"
MC: "Yeah, actually I do."
