Nothing like surviving a traumatic deep space event involving a murderous xenomorph then hypersleep for 57 years to mess up your sleep cycles huh? When Ripley finally made her way back to earth, she had a few issues to work through, not the least of which was the nightmares. This one in particular, expertly recreated by Grantmasters, would be enough to rattle anyone.
One of James Cameron's true gifts is introducing technology that not only looks cool, but is plausible. You can really believe in the Power Loader. I can still remember watching this thing in Aliens so many years ago and just going "awesome" (with that sort of giddy little nerd dance you do in your seat). I really want to walk around in one of these some day.
There are few epic climax struggles more memorable that Ripley vs the queen alien in Aliens. And now we can admire it in CubeDude form thanks to Lego-Man-at-arms. The super deformed power loader cracks me up.
