I'm only grading the ones I either have, or have seen in person:
Graduation Day Buffy - 7.5 This is probably a bit harsh because I think the likeness is very good and the clothes are very accurate from what I remember. But her face is kind of "Zombie-ish" to me. In some ways I wish I had gotten Prophecy girl and put her in the Grad Buffy's outfit....maybe I just like the rooted blonde hair better.
Becoming Angel - 8. I feel the headsculpt captures Boreanaz but I think the face is too thick for his look in "Becoming", which is the episode this figure is based on. He looks more like Angel did on his own show. It's funny, because I feel the Angel from "City of" really captures his "Becoming" look. The thinner face with the smirk. This figure would have scored a 9 if it wasn't for the "City of" Angel. That one just looks too good.
Human Spike - 10. As perfect as you can get him. The sculpt is dead on, it captures Spike 100% and the costume is great. Probably the best figure in the Buffy line.
Drusilla - 10. A personal favorite. I love the sculpt of the hair, and even with the vamp face, they captured Drusilla's beauty. The clothing is top notch, and she has great accessories. Definitely up there with Spike in this line.
Xander - 7.5 I think the look of the figure is pure Xander. But there's just a little something about his face shape...I don't even know what it is....
Faith - 5. Just didn't capture Faith, not Eliza Dushku's likeness nor the "presence" of the character. This one upsets me because Faith is in my top 3 favorite Buffy characters. I love Faith. I'm not really crazy about the outfit they chose either. Kind of boring for Faith, even though it's episode accurate. But if she wasn't in the package and had no accessories with her, I wouldn't know who she is.
Willow - 4.5 You can see Willow in there. But I can't ignore the warping of the head, and she looks cartoony in comparison to the other figures.
Vampire Willow - 9. Good vampire sculpt. I think they did a good job capturing Doppleganger Willow. Not quite as good as a couple other vamp sculpts, but still very cool.
Vampire Buffy - 9.5. Best Buffy likeness, except she has her game face on. But it's a near perfect sculpt of a vampire SMG. And it has one of the coolest exclusive accessories (the headstone)... .5 was taken off for the outfit (the pants are too baggy) and also because I can't give her the same score as Spike & Dru because I don't think she's quite that great...
Vampire Darla - 4. The headsculpt is just too elongated, and the expression on her face is not menacing enough. I think she looks odd, personally, and someone here mentioned Eric Stoltz...that's a likeness I definitely see. I just don't see Julie Benz. I also really despise the school girl outfit.
Liam - 7.5. Not my favorite look for Angel, but a great likeness and a great outfit.
*Edited to add a couple more I forgot.
