Its very disconcerting when you find a fic that you KNOW you should hate, everything about it being just WRONG and have to admit that it's a stunning piece of work. My worst experience like that was a Snarry fic [I loathe Snarry] with Sev having a relationship with 10 year old rent boy Harry {ewwww, just *writhes in distaste*]. I was shocked to find it one of the most moving fics I'd ever read.
