I can't speak for the new Mirkwood Elves, but my experiences with Hobbit finecast haven't been at all positive. Of the three miniatures I've bought so far (the first Thranduil, Thror, and Young Balin), all have needed resculpting and patching, and the Balin I even returned as his face was completely messed up. Some finecast miniatures I've purchased have been successful though, including the High Elf Everqueen Handmaiden from Warhammer, which had almost no defects at all. I think it's essentially down to your luck in which blisters you buy. Some might have imperfections, some might be simply unacceptable, and others might be flawless.
