Higurashi - One of the best. Story was excellent. It seemed really well made too. It, uh, Gets kind of gruesome though.
I 100% agree with you on this. I got my mom hooked on it, too. I was over yesterday and we watched like ten more episodes of it. A lot of people seem to hate the dub on it but it doesn't bother me at all. I watched the second and third seasons subbed and don't really have a preference as far as casting goes (but some of the translations in the subs are really, really bad. fansubs

)
EDIT:
I've been watching a bit more anime lately, but pretty much only the ones that are on hulu. Demon Lord Dante is pretty good (although the animation isn't that great), but apparently it's just a more confusing Devilman (which I haven't seen).
If you haven't seen Now and Then, Here and Now, do yourself a favor and watch it. It's only 13 episodes long and it's really good.
Other than that I've just been finding anime that's probably really terrible but is entertaining to me. I watched both seasons of Ah! My Goddess, for example.
