Far from being a good entertainment, this OVA is for MegaTen die-hard fans, mostly because it was where everything begun, not only for the SMT series, but for the whole JRPG niche. It is said that Dragon Quest V started with the whole catching monsters, befriending them, but in reality in 1987, 5 years before DQ5, the very first megaten game was released based on a trilogy of japanese books. The plot? Summoning demons through OG computers.
Can't really say its bad adapted since the first book which is the whole ground for this OVA has more than 450 pages, so if there isn't any prior knowledge of MegaTen it might get confusing.
What's best about is the darkness of it, megaten always had this feeling, this vibe of something obscure, but it kinda lost that throughout the years, don't get me wrong, it still is, hell yeah. but when you watch this you kinda realize how heavy the stuff in it is, i read that since it was made in the late 80s, it was aimed for the adult audience so they didn't easy any of the stuff from the books.
Will recommend DDS to someone who played the games and fell in love like I did 1 year ago, most likely through Persona, which is way lighter than this one. Won't recommend to anyone who found this randomly, is isn't a masterpiece, it isn't good, is a well-written MegaTen OVA poorly done made for fans.
