DoS definitely fits this. It was just a poor excuse to reuse Soma. IMO, AoS was a nice end point on the timeline. AoS gave a sense of finality. Soma, Dracula's reincarnation, was destined to be the "new" master of the castle and essentially where is previous life left off, but he fought the Chaos in the Chaotic Realm and freed himself from his destiny, which seemed to me a nice end point for the timeline. DoS pretty much said: wait, he didn't free himself from his destiny and could still become the dark lord. Not to mention, the story of DoS sucked. Some random cult is trying to create a new dark lord because while they fear the dark lord and worship God, the belief there needs to be a being that is the direct opposite to God. But, since when was Dracula the opposite of God? Before DoS came out, Dracula was just a really powerful vampire who sought the extinction of humanity.
As I said, DoS was just a poor excuse to reuse Soma and the AoS soul system. Oh, and let's not forget the unnecessary seals using the stylus for boss fights. Those were just an excuse to use the DS's stylus and dragged the game down even further.
Rant over.
