i irrationally hate the actor that played the mother from How I Met Your Mother. Maybe i just hate that doe eyes look she seems to be inflicted with. And she seems to always be playing some sad sack in a bad relationship so it might just be type casting too. Plus the end of HIMYM was so fuckin bad so that might not help lol.
