My expectations were too high because of the movies, it's not bad, by any means, but I remembered it way better than what it is (probably because of the animation of those).
One of the reasons is, almost the whole route plays in Shirou's house, any bit of action that occurs is when a Servant dies.
This isn't too bad...but compared to Saber's and Rin's route it just falls sort. Anyway, this route is pretty wild, Shirou is forced to ignore his ideal (which if you are playing this, you know how important that is to him), they even kill a certain Servant which to this day I can't believe they killed, what happens to Shirou's arm, a multidimensional sword, like dang, if only Sakura wasn't such an awkward villain (I mean, she never wanted what happened to her, so I guess it makes sense).
Also, this route has some Tsukihime paralels, dark story, someone killing people in their dreams, blood sucking, and sex, this one has a lot of sex
