I searched the annals of the books subreddit way back when and could quite literally only find one other user besides me who couldn't stand A Man Called Ove by Fredrik Backman. I tried two separate times to read that book and just couldn't do it. I understand the premise of crusty old guy is soft and mushy on the inside, but ffs he is SUCH a massive prick in the beginning I just could never get past it. I also read Anxious People by him and couldn't stand it, so I think maybe this author just isn't for me.
Super noteworthy wise I quit A Tale of Two Cities on like page 4 lol, but that was more because I didn't understand that style of English than anything else.
Just out of curiosity what was it about Piranesi you didn't like? I've heard it recommended on the books subreddit so many times so I'm curious.
