I absolutely cherish this film!!!
I can't remember a time in my life where this has let me down. I've watched it close to a thousand times and enjoy it thoroughly everytime.
The introduction of the USCM is one of its crowning achievements. The galaxy's most bad ass hombres to ever sail the cosmos. It is an utter shame though they only debut and star in this film.
Alien was superior for its horror connotations but Aliens manages to compliment the series with a spectacular action flick.
