I highly recommend Fate/Zero (even to people who don't really watch anime). 7 masters and their servants fight it out in an epic war for the Holy Grail. No fanservice, no harem no anything, just pure storyline/battles and one of the highest budget I've seen used in anime. It's a tragic story, but very good. (to fans: had to type this out after watching Berserker hijack a F15J fighter jet and using it as his Noble Phantasm. Epic -_-)
