Not all great films need a sequel. Somtimes it doesn't matter what the fans think or how much profit a studio believes they can make from a sequel. Ghostbusters is the perfect example of this. The first film didn't need a sequel yet one was made. Most fans hated it and the movie was somewhat of a financial disappoinment. We have not gotten a ghostbusters movie in 18 years for good reason. Furthermore, Alien 3 turned out to be very unprofitable for fox. Unlike it's predecessors this movie barely made back it's budget from the domestic profit. The series should have ended with Aliens. Lets see alien was very popular, alien 2 was also so why wouldn't a 3rd one be made? A third movie gave the viewers closure to Ripley's story.
I don't think the premise was good and don't see how it could be executed much better. Any director would have it difficult to make a good film out of that crappy script. Im not saying just one thing was wrong with it, im saying the idea was good but everything else wasnt too par.
You are comparing apples and oranges. Yes, alien and aliens were depressing. However, at the end of each movie Ripley is left in a situation were there is hope. There is no hope for her in Alien 3 because she is dead at the end!!!
Every trilogy needs an ending, the intent of a3 was to complete ripley's story, hence her death would mean no more ripley in any other alien sequels. So yes 1 and 2 end in hope but 3 chose to kill her off to secure that she wouldnt be back for another film.
This is my last contribution to this thread because it is pointless for me to continue expressing why Alien 3 is the worst aliens movie and worst sequel I've ever seen. I've provided more than enough evidence for why I have these feelings.
My post wasnt even about which was better A3 or AR I stopped arguing that when I stated which movie was the tallest piece of crap.
