Muß das sein? 
Only sequels and prequels and remakes from Hollywood currently, it seems. Alien 3 already was boring. Alien 4 simply was terrible. Terribly bad, that is.
Wise decision by Ridley Scott not to direct, and leave producing it to his brother (financially it probably will be reasonably successful, since curiosity will drive people into the cinemas). However I wait for Ridley Scott's realisation of "The Forever War". That could become a feast, eventually. He tried 15 years or even longer just to get the rights, it really is heart's business for him, he said.
