of course, as already said. ive never cried as much as i did watching through clannad and after story. its like the only point of a number of episodes is to build up to an event that is going to make you tear up lol.
i had some teary eyed moments during kanon (2006) as well.
again with Air..
not only are they good for the aspects of teary eyes, but i really liked air, kanon, and clannad immensly. definitely up there on my fav lists, and there all done by kyoto animation which is an amazing team.
theres some good movies.. 5 centimeters per second, grave of the fireflies, the girl who leapt through time has a moment or two.. hrm. im sure theres more i cant think of too
