I have watched this movie when I was a pre-teen at the cinema, and MY! It completely blew me away. It has got my adrenalin pumping so hard that I almost wanted to slip back to my seat and take a breather! Although during that time I didn't quite understand most parts of it (too young to understand), I was deeply immersed into such rich story-telling and the fantastic alien creatures. The tensely build-up atmosphere and the space-ships, grips you so tightly it seems never to let go.
This movie rocks, scares you right on to your face, very mysterious, have tons of special effects (not quite CGI though, but the mechanical aliens looks just so threatening and scary). James Cameron is such a fabulous story-teller in this Sci-Fi stellar! The movie ran at more than 2 hours but I didn't feel that at all. Actually James has cut out a lot of scenes for this theatrical release back then, but you can still get those scenes back on the DVD (extra 17 minutes footage).
The acting is good especially from Sigourney Weaver, Paul Reiser and Lance Henriksen (as the robot). Sigourney's Ripley is such a strong-willed woman, that even put shame to men (somehow I feel this is quite unbelievable, because she has got so much energy, especially the scene where she gets back to the Queen's hatch to save Newt). I have watched other alien series (Alien legacy - All four parts), but I can say this part 2 of the series is my favourite, followed by Alien, then Alien:Resurrection, and lastly Alien3)
I am quite happy to see this film stays high at one of the top Sci-Fi movies in IMDB)
Till now as an adult, I still go back to watch this DVD occasionally and every time I watch it again, it brings in a completely new scare, and new thoughts, also the new meaning of what is a horror movie all about!
Highly recommended if you haven't watched this yet. I give it an 8 out of 10! (Truly deserves the high IMDB rating at 8.2 to-date)
