I previously listed Mermaid's Forest and Scar. <_< Btw, those were OVAs not movies. I agree the entire Mermaid Saga is dark and I like it! Finally something not filled with shojo elements, for more mature viewers. Rumiko can do the horror genre certainly, but she chooses not to. As for Miyu I prefer the Mermaid Saga better b/c it is considerably darker and twisted.
Normally OVA's (original video animation) is also known as 'movie'.
Did you watch the original OVA or tv series or both?
I also agree that mermaid forest is better than miyu as mermaid forest is more of an adult content animation.

Saw all of them. Prefer the OVAs and to be honest the mangas better than the tv series. Much more attention to the character development and the consistency and care Rumiko uses for the mangas. Though I will admit I am glad the tv series character designs are closer to the manga when compared to other series that later become tv series. Ugh to Lodoss Wars tv, Tenchi tv, Bubblegum Crisis tv, Sakura Taisen tv, ROD tv, etc.
Also, OVAs are usually independent of movies, simple indicators are the length of time, budget, and the quality invested. In the past I can understand how there might be some confusion b/c some series used the terms interchagably. I.e.the City Hunter Specials were actually movies, but were also classified as OVAs. This can be confusing to say the least. Even some older series made this distinction, i.e. the granddaddy of series Urusei Yatsura OVAs vs. the first six movies. But another important distinction is that most OVAs to the best of my knowledge and belief, were not shown in threaters in Japan. I've read some were used in double features. Can someone verify this?
In any event, anime movies especially nowadays, are clearly distinguished as movies and not OVAs. Case in point tv or OVA series that eventually add a movie: Cowboy Bebop Knocking on Heaven's Gate movie, Appleseed movie, Full Metal Alchemist movie, Ghost in the Shell movies, Inuyasha movie. The list goes on and on, but generally for the newer animated films, studios do make the distinction. IMO that's a good thing with the global marketplace for anime growing at an astonishing pace.
