I just got Hicks and the Alien Warrior, so I figured I'd share my 2 cents...
First off, I love 'em. I really truly do. The articulation is fantastic on both Hicks and the Alien, and you can easily get some awesome poses. This paired with the sculpting is a home run combo! Additionally, all the little accessories and fine details on Hicks (and Hudson, though I don't have him...yet!) is great as well and really goes that extra step forward.
However, I also ran into some QC issues, mainly on the alien. Now, when I pick my figures out I do what I'm sure we all do and that's checking the paint jobs and any noticeable QC problems. I typically look to see if any parts are damaged or missing, the least warped one, etc. So for the Alien, I wanted to get one that wasn't overly brown and so I found one. Upon opening him up, I noticed the jaw was kinda wonky, like lop-sided. As a result, the jaw doesn't close correctly and the teeth don't clench like they should. OK fine, but then I see that one of the little 'tendon' thingys on the sides of the mouth is cracked. I don't want to mess with it for fear of breaking so it is what it is. Since he was kinda turned in the package, I didn't spot any of this.
Hicks is fine in terms of joints, no breakage, etc. I had more of minor paint issues but a few of which really annoyed me. For example, most of the little silver 'snaps' or buttons were applied just off the mark and so there are a bunch of little silver circles where they shouldn't be...one that was particularly frustrating should have been next to the "born again" text, but instead was applied right in the middle of "again" UGH!
now, you may look at my post and see that I wrote more about the negative than positive. Despite all of the grips and nit-picks, I really do love these things. I'm eagerly awaiting Hudson and everything else on the rise. Really hoping we get more actual Marines; Drake, Apone, Vasquez, Gorman, etc. And an in-scale Queen? Fantastic.
I'm confused on the Sigourny thing. Didn't she allow her likeness for the mattel Ghostbuster figure, and some Avatar figures? You'd think if she allowed it for those then she'd sign off on Alien...
