The problem with vampires in Oblivion was that they where supposed to be able to pass for a human when fully fed, I don't mind the visual effects when not feeding for a long while, seams only fitting, but in reality they simply destroyed the character face altogether, while by my deep believe the 100% vampire should have looked exactly like the character I created. So no more random face mutilations please.
lich freak - Morrowind vampires where uncontrollable, true, but hideous? No one sad that

And Skyrim vampires are not necessary hideous - scary, yes, strange and otherworldly looking, yes, weird eyes, icy skin and so on, but no one sad they can't look good it their own scary way

P.S. Not a Twilight fan btw, never even watched that teenage drama, but I love World of Darkness and Masquerade

And there scary and unnatural not always equals agly, I'm a big Tzimisce fan
