The leadup to Dracula. It doesn't make it a worse game obviously, but common, look at this compared to the past:
CV1- The music changes and you're at the stairs; you KNOW you're finally at the end.
CV2- You go through the ruins of CV after destroying Drac before, and its a mysterious theme, fantastic buildup (hate when ppl complain there aren't enemies here)
CV3- Same as CV1, classic
CV4- Best IMO. Goes quiet after beating death, blocks fall, you go up, down the dark hall and the torches light as the music changes to a sped up version of the intro(in the US version anyway). It's so superbly done.
X68000- Lazy copy and paste hallway, few enemies, no music change, just get to the famous stairs. Woopdy doo.
It's the 1 time the game feels lazy. Like I said, doesn't make the game worse at all, its just such a disappointment. Pretty much all the other linear CV games make a big deal about getting to Dracula (besides the Adventure)
