Query: Makes the series worth it.

Now this is an example of what the Alien series is capable of. Dark, atmospheric, intriguing, and boasting better performances than any of the other Alien movies, Alien 3 shows what an Alien movie should be. The first film was notable for the creature and little else. Aliens was plagued by over-commercialization and a weak final half-hour. Alien 3, on the other hand, focuses not on continuing the series, but rather on being an intelligent movie in its own right. The film more than overcomes its few dialogue faults and has quite possibly one of the greatest endings thus far committed to celuloid.
