The one I REALLY can't stand is Rosetti, because he can neither draw nor handle perspective. More or less a poseur.
But Holman Hunt has his moments.
I don't like the pre-Raphaelites very much; too much detail and distraction for me, I think. Also, I never got how they were like the "primitives" before Raphael. They always seem super-sophisticated to me. Some people swear by them, and there are some good pieces (like Rossetti's Annunciation below). I guess I just like simpler works.
