Ok, there is few things that I want to clear:
With the exception of sony no other company has had a castlevania game worth mentioning on their hardware. I'm not even going to consider that new game part of castlevania because it pisses me off kind of like the ps2 games but worse.
So, according to your statement, Castlevania 1, 2, 3, Super Castlevania 4 (that considered by many people as one of the best games in the series, next to SOTN), Rondo of Blood, Castlevania Adventure 2, Circle of the Moon, Aria of Sorrow, Order of Ecclesia are all not worth mentioning.
Did I understood it right or there is some miscommunication problem?
Because if I understood what you have written, as it is, it basically means that according to yuor words, most of the series is crap and even games that appreciate by practically every single fan, is shit an there is only SOTN and nothing else?
Nah I have to say bloodlines was crap but more because the sega was crap. The sound is awful and the control is pretty bad too. It could have been a lot better on different hardware. But the story is pretty bad too.
While I personally not big fan of Genesis, and there is some things that I dislike about that console I must say that Bloodlines was one of the best classicvanias in the series. In terms of graphics it was very good. There were ceratin limitations, but Konami managed to work around them and make the game good looking. Also the game was rich in special effects, even more so than great SCV4.
Gameplay was interesting. The idea take action from the castle was awesome and it's sad that it wasn't used very often in the series.
The only thing that was not so good about this game, was music, but in the end it wasn't very bad. And some compositions actually sounded very nice, even taking Genesis specific sound hardware in account. Certainly not horribly jarring or annoying.
