it's the first and it's still the best in the series.

Rating: 8/10 (29 April 2000)

the aliens franchise is a good example of the fact that the first in a series can virtually never be undone.one reason for this i believe is that the success of 'alien' was largely due to the fact that knowledge of the alien was limited and we never did see much of it.this created great tension and suspense because we never knew it's capabilities or where it would reappear.sequels lost this advantage and relied on a higher body and alien count.this is also the reason why 'halloween' is also by far the best in the series.
