I'm torn with this one as I just received it yesterday. Here are my thoughts:
Pro
Size-it's not too big that you can't put it anywhere. It's big enough to have some good detail.
Sculpt-it's actually a pretty good pose and there are a lot of good, and tiny, details in this.
Base-I personally really like the artistic aspect of the base. Looks very Giger-esque and I like how the top looks similar to the Queen's head crest.
Con
Scale- this is not 1/5th, not even close. I have the Wolf 1/5 statue and was hoping to pair them. That went out the window immediately. It's bigger than a Hot Toys figure, but not 1/5th.
Weight-this can be a pro as well, depending on your point of view. It's light, I mean....very light. Which could be good if you want to display it on a shelf and are worried about weight. The figure itself is just as light as a Hot Toys figure. The base has some heft to it, but is also very light.
Materials-PVC...PVC...PVC. Nothing else to say. I believe most of the base is also PVC.
All in all, I'm 50/50 on this. If it was only $250-$300 this would be a no-brainer purchase for an Aliens fan. But, it wasn't.....
