You said that you considered cleaning your shoes more entertaining than It Comes at Night, which implies that you thought it was as boring as an actual chore. I, who did consider it a reasonably effective film, made a response where the subtext is "if you think cleaning your shoes is more 'entertaining' than this movie, then you must really have some interesting shoes to clean" - and, since we're talking about a horror film, the "f*cked-up" is supposed to imply that the shoes are even more horrifying than an actual horror film.
That's how you read between the lines.
