Well I kind of liked it, the short lenght was to be expected. Still the final bossfight was nice. I found the lack of projectile attacks somewhat annoying, same with alucards powers, you could just not use them in combat. Wolf form maybe, but everything else was just there for puzzle solving.
All in all I think I got my moneys worth out of the game and the dlc. I really don't think there needs to be more closure or anything since pretty much all points have been covered, I really don't understand all the fuss about the ending.
