SPOILERS I'm not really pro-Saber as I think shes a bit bland in comparison to the omnipotent Tohsaka Rin but I'm really glad the anime chose the Saber route. It gives the whole thing a lovely sense of innocence and tragedy that none of the other girls could quite grasp. The biggest annoyance is Shirou's ignorance in refusing to let Saber battle (I like to call this Haruno Sakura Syndrome, when a strong female character constantly has male characters throwing their bodies in the way as human shields, preventing the girl from showing what they're made of.) Though his ignorance causes more problems than it solves, its a great seeing the respect build between them. People were disappointed with Stay Night's ending because it didn't give them the Avril Lavigne happy ending they pined for but I was satisfied. Stay Night is a tribute to the fact that happy endings aren't always about finding love but also losing it, accepting it and finding a way to move on with your life.
