I 've seen plenty of interviews with the creative team on A L I E N, who simply, diplomatically, state that it's not their sort of film.
It's just not my sort of film either.
If Blomkamp can do something interesting, then I'm open to seeing what that is, but if it's a story that relies on bringing back characters in order to rehash, or get different closure, on Aliens, then it simply won't interest me.
