Absolutely love this film, one of my favs of all time. Loads of great characters and lines, and the sfx still hold up today, which is more than be said for a lot of the dross out there (i happened to catch a bit of Phantom Menace on TV the other day, man that dated horribly!). Gotta love Macready and the gang, many of the infamous scenes and lines have already been mentioned, although the autopsy always stuck out in my mind as a great scene as well, particularly the gagging by the doctor whose carrying it out!.
Never saw the prequel, heard so many bad things about it, always had in mind that they would make a sequel whereby the radio operator (Windows?) has actually managed to get the message out, and once the storm clears a rescue team from McMurdo Station which is much larger (~250 inhabitants) comes to get them, possibly led by some form of military (I believe it's a US base so they're bound to have an armed presence
). Of course, Macready and Childs are still alive, although Macready is unresponsive so they take them both back and, well you can imagine how it continues from there!
**Spoiler Alert** You just know Childs was infected at the end of the original, although it's never revealed, else where did he go during the climatic battle? It's probably a bit late to do the sequel now so we'll just never know, but I always had it as the transition a la Alien > Aliens
