If traditional gothic vampires are your thing then Seraph is probably not for you. There is little in the animation that is dark and sinister and this probably owes to the bright colour palette and the relatively weak soundtrack. The show is a fantasy-style blood fest rather than a true horror and should be categorised as such in the mind before viewing.
All of this said, despite it's lack of visual edginess, it is an anime that has strong characters with likeable personalities and a strong sense of family, loyalty to friends and duty at the core of an entertaining storyline.
If I'm honest, I wasn't expecting a lot, so I was pleasantly surprised by how engaged I was in the storyline and I enjoyed the series in the same way as I enjoyed the film Underworld.
Admittedly, what was supposed to be a twist was easily fathomed early on, but there are some books that aren't epics and are nevertheless page turner's. For me this was the anime equivalent.
