I'd be terribly concerned if you had watched fraken fran, considering it doesn't seem to have received an anime adaptation
S'got (a completed) manga and an audio drama, near as I could tell, but nothing animated.
Still. Can't actually recommend it, due to its content, but I will say it's pretty much the only guro-style/focused piece of media I've actually enjoyed experiencing, pretty much ever. If you can stomach that sort of thing, it might be worth having a go at.
I'd recommend it. The reason its more palatable is probably that unlike other guro it doesn't take a nasty/sadistic tone that makes you cringe. The frankendoctor in Frankenfran is actually well-meaning and cheerful and honestly believes she's helping people. So it's a gory black comedy rather than strict horror.
In the news recently, there's an American live action film production of the
Tiger and Bunny anime in the works. Ron Howard is producing it. Along with Ghost in the Shell, that makes two seinen type animes that have been announced as getting the Hollywood treatment, which is definitely a new development.
Concrete Revolution, Nanatsu no Taizai, Akatsuki no Yona, Death Parade, or the adaption of Assassination Classroom? Getting bored rewatching through the long slog of UC Gundam again, so I'm willing to give anything half-decent a shot.
Death Parade is the best of that bunch. Definitely worth seeing, it's a really unique series concept and execution.
Akatsuki no Yona is basically light fantasy with an interesting setting. It's like the shoujo version of Arslan Senki basically, quite similar in terms of overall plot. Except for the bit where there's romantic tension between the lead charater and the main warrior dude. Arslan Senki doesn't have that.
Nanatsu no Taizai is an over-the-top shonen type series. Reviewers compare it to One Piece or Fairy Tail. I'll definitely say the show is completely bonkers, the fights are insane and it never got boring or predictable. It has another season coming next year.
Assassination Classroom was pretty good, but I don't know the manga so I can't say how they compare
