Alien was pretty scary, right?  So, how do you top it?  How about a whole bunch of Aliens?  Thankfully, the plot of this 1986 sequel is a little more inspired than that.  After a very long hypersnooze, Ripley wakes up, gets fired, gets a crappier job, then gets a dangerous and scary job facing her worst fear: Aliens seeing her in her underwear.  But fear not.  She's got a company of space Marines, one of which has future Terminator combat experience, so she's covered.  Aliens, directed by James Cameron, was an adrenaline rush and chock full of unforgettable thrills and dialogue, and was mostly a worthy successor to Ridley Scott's original.  Mostly.  Xenophiles, this one's for you!  Let's rock!
