Is it just me or did it seem like he wanted to make out with Ripley? :
Seriously though no one thought it was odd that it didn't try to kill her?
There are two reasons for that. One Cameron changed how it moved around. In the first one only it walked like a biped, on it's back feet. Then in this one, it's evolved from an animal so it's even more beast-like.The single Xenomorph in this film works very fast by comparison to the one in the first.
I also love how that one guy had a cigarette near it... :
That was one brave asshole. Poor guy.
This is one aspect that needed to be in the final cut. That guy is insane.
