Princess Mononoke, is probably the hardest to watch, just thinking of it gives me the chills; well to me at-least, its pretty F'n scary.
Hunter D was good too, liked 1's story better, but the artistical value on number 2 followed by its good music that just gets loud out of no where scaring the crap out of you, made it a good follow along. In fact, even on the DVD the actual movie running time's normal conversations are so soft you have to turn up your volume; but when some sneeky action comes exploding out, I'm sure your neighbor will call the cops thinking someone is really getting killed. lol But if you get any good DVD movie now days, like the ones I've named; the trailer option should always show good movies too, I dont have any of them any more, so my memory is kinda foggy.
Bio-Hunter was pretty good too,

A few nudity scenes; but nothing too adultry.
Others I wont name because theres to many scenes of monsters raping humans in full out hard core porn style...good movie story lines, but just a few in between stuff thats too adultry showing everything; not to mention I'm not into anime porn, I just like the good ones that have good story lines and memroable charecters.
