I'm actually with Masta' Bo on this one. I mean, the new hairpeices are nice, and do allow for more variety, but you have to ask yourself- do we really need some of them? I mean, Bellatrix's was probably necessary, but wouldn't the french braid hair work just as well for Ginny? And did we need new hair for Draco? I mean, sometimes new molds are necessary, but isn't it part of the charm of LEGO that certain pieces have so many different uses
Of course, it's not nearly as bad as the faceprints. For the most part, they're okay (Really like the new Ron and Hermione faces), but some of them look just awful. Draco's got a grin on his face that makes the original Han Solo face look sly, Mrs. Weasley looks like a man, and several other faces just look like they've got way too much detail going on. For the most part, I prefer the original figures.
Well, anyways, the sets do look nice. I was always a huge fan of the original Potter line mainly for the look of the architecture in the castle sets, and it looks to be just as good here. A shame that they're not going with the whole "combine the sets to get a bigger castle"-type thing, I really liked that about the original sets.
Oh- and I lol'd hard at the angry monster face on Aragog.
