Received mine today as well. About 40 twist-ties later I freed the beast, and he is huge. Sculpt is fantastic. I didn't need any hot water, I just jammed his legs in there. Cut joints kinda stink, but hey, this figure is 22" and cost only ~$40, and the sculpt is preserved well. The skull paint looks like it was done with a sharpie marker (really the only thing I don't like), so ideally I'd have liked the dome smoked a bit more to hide that.
Anyone interested in customizing can dremel the inside of his lower jaw a bit, and the mouth should close all the way, unless the main jaw teeth get in the way. The tongue jaw is just open too wide for the mouth to close. If the tongue itself was shorter, it could probably recede further back into the head. I can get mine closed almost all the way anyway.
Overall it is an awesome figure...this thing definately has a presence in the room. Minor customizing will make this perfect. Anyone on the fence should go buy it now!
