At least we can all agree that the Bloodlines saga created more problems than it ever solved.
To be honest, Bloodlines should simply have been retconned. All Portrait of Ruin managed to do was to enlarge an already gaping plot hole; and now that OoE has actually built upon it, that makes three games that need to be weeded out for the canon to start making sense again -- unless a future game manages to tie up all of the CV canon's loose ends. I'm honestly more partial to the the latter option, but I'm not seeing that happen in the near future.
Why is there any need to retcon Bloodlines. It came BEFORE the whole 1999/Julius Belmont thing was even concieved, as well as SotN(hell, it even predates Legends, which WAS retconned, though came out banking on SotN considering it used the SotN designs of Alucard and Dracula as the basis for it's depictions).
That being said, the presence of the Morris clan within the CV canon isn't that much of a deal. ESPECIALLY what Bloodlines brought forth. It's what IGA wrote, as well as what was wrote with PoR that messes things up. Now, IGA wrote Julius Belmont to be the one who finally defeated Dracula in 1999, which contradicts that already established Morris clan being present in Bloodlines, BUT IGA came up with the idea that the Belmonts had to go into hiding until 1999, so naturally the Morris clan had to step in and take their place, being blood relatives. Note, at this point, IGA did NOT say the Morris clan was inferior to the Belmonts. For all we know, they could've been estranged from the family business over centuries, yet still harbored that latent power to fight against evil(while those of the main branch have been training for centuries and are primed for fighting evil, but due to what ever prevented them from touching the VK, they can't). Hell, he could've came up with a GOOD reason to explain everything without downgrading the power and importance of the Morris clan(hell, I could've). But then, we got PoR, which explains why the Morris clan is inferior to the main Belmont branch, and that's about it(story-wise, is doesn't offer much).
Call it one of many occasions that IGA dropped the ball. We could've gotten a great follow-up to Bloodlines that went more into depth regarding the Morris clan, their history, how they split off from the Belmonts and how they came back into the family business. Especially some more interesting ideas considering it took place during WWII, like the previous one took place during WWI, and had you running across Europe in the process. I think many of us just wanted something fitting of the great game that Bloodlines was. Other than that, while I love OoE, IGA dropped the ball regarding tackling WHY the Belmonts have to go into hiding. First hearing that, I always pictured something like the Belmonts being tainted to the point that they couldn't LITERALLY hold the VK, and it would take over a century to cleanse the main Belmont family line through generational meditation just so, eventually, a Belmont can be born again without the "taint" and can wield the VK. I pictured it some big conspiracy of Dracula's followers, so pissed off after all the defeats, to curse the main family to the point that they cannot wield their weapon(the only weapon capable of killing Dracula), hoping that this cripples them and allows a time period where Dracula CAN come back without a VK wielding Belmont to counter him. Of course, they don't count on the Morris clan, who the Belmont's contact(finding them in America), and call their asses to Europe to help stop Dracula while the main Belmonts seek a means to break this curse/taint. I know I rambled, but OoE only briefly brushes over that. We know something happened and the Belmonts were sent scattering throughout the countryside, and eventually you have to gather them to populate Wygol. LOL! Really not important. The story is almost as pointless as PoR, but it has the good case of being both a good game and not making you feel dumb over the whole "Morris clan is inferior".
With CV, games that don't contribute ANYTHING are looked upon with "meh, it's alright" type attitude, but ones that bring in sort've loathed concepts and ideas(PoR's "Morris clan is inferior", Legends' "Trevor is Alucard and Sonia's son, and Dracula's grandson") are pretty much scorned. I find that a bit funny. A game that does nothing new is held in higher regarnds that one that tries to push a new idea(well, in some cases).
