I watched the anime before i even knew there was a game of it and i was really dissapointed. Music was top notched, but almost everything else was...fail.
The story by itself was decent, but the bits with Akiha in it didnt make any sense at all. It was like they threw it in to make the viewers think Akiha might be the vampire for like...one or two episodes. That part would have been better if it was developed into something further, other than "i have special powers and drink blood lulz".
Akiha's hair going red at the bridge was pretty cool, and the viewer thinks hes going to see Akiha pull out some major h4x...then she gets insta-defeated off screen.
And the exact same thing happened to Ciel, a vampire hunter who is apparently weak sauce.
It was like they ran out of budget and couldnt animate the fight scenes against Roa.
Then there was the art(man-faces on all the women...), and plot holes...Arcueid later tells Shiki shes this powerful vampire...which makes NO sense since she ran from Shiki yesterday, and hes just a normal human.
And Nero? Arcueid makes him out to be some major bad ass, and he takes out an entire hotel in no time. At the fight scene i was expecting some major epic fight lasting 2-3 EPs. Instead Nero just let loose a few dogs, then got stabbed once by Shiki and died.
And i couldnt understand what the deal with the sacchin love triangle was. Was the director trying to make us sympathize with her or try and create a romantic triangle sub-plot? Whatever it was, it didnt go anywhere, since all we get are hints that sacchin likes shiki, and...thats it, until the rooftop scene.
