It was speculated, it was considered, it was argued, now it's official: Neill Blomkamp is making Aliens 2. He's going to disregard Alien 3 and Alien Resurrection and make a 'genetic sibling' to Aliens, one that Sigourney Weaver says will 'properly finish' Ripley's story. Which is weird, because it was pretty properly finished in Alien 3, but I guess that was too much of a downer for everybody.
It's Superman Returns all over again - ignoring the second two films in a franchise and chasing after the aesthetic and feel of a much older film. Will Blomkamp approach Aliens with the kind of reverence with which Bryan Singer approached Superman: The Movie, and the kind of reverence with which James Cameron did not approach Alien? Look, I've said this a lot but what makes the Alien franchise special - in both its successes and failures - is that each film is not the genetic sibling of the last. It's almost like an anthology series with continuity, and it would be so cool to continue that as opposed to aping the second best film in the franchise.
As Russ Fischer at Slashfilm points out, Weaver's comments are kind of shrugging off her role in the last two films, as she wanted no guns in Alien 3 and wanted Ripley to die. Weaver already called for an end to Ripley's story and got it!
I'm sure a lot of people will be happy that Alien 3 and Alien Resurrection are being ignored, but I hate this kind of laziness. If you're taking on a sequel and not rebooting the property you're basically playing Exquisite Corpse. Your job is to pick up the threads left and weave your own story - then leave your own threads for someone else to keep weaving. That is such a huge part of what I like about these films, but here's Blomkamp, unwilling to work at it, just hacking at the Gordian knot of Alien continuity.
Here's the video where the two speak about their plans:
