I opened up Jedi Luke, Chewbacca and Darth Vader tonight. Initial thoughts:
Chewbacca is terrific, the sculpt and paint apps really seem to mesh well here and even the elognated neck isn't too annoying. The eyes on mine were pretty on point, but still seemed to be the weak point somehow. Maybe the pupils are too small? Sounds silly but it's the only thing that really bugs me about the figure.
Jedi Luke is growing on me more than I thought he would. You can get a good range of poses out of him, and the two handed lightsaber grab is no problemo. The face sculpt itself is ok, but again the eyes are the weak point here. He's got a real case of puppy dog eyes, but even worse, no matter how you position his head he always looks like he's just staring brainlessly at nothing. Obi Wan had a similar thing going on. I think a scowl would maybe come across better.
Vader bugs me. I noticed in the package his helmet was slightly ajar and after opening him I found I cant really keep the mask pressed down tight to the bottom piece. It keeps floating up and looks stupid. A separate old Anakin head would have been a much better way to go. On the bright side, the cape sewn through the chestplate isn't as atrocious as I suspected it might be. I was able to drape it over his shoulders in such a way as to hide the strings. I gotta jimmy with those inner robes though, they definitely do not look right around the codpiece. And yeah, he needs a neck. It's an ok figure overall, I just wish they had done a little better job with arguably the central character of the whole franchise.
