No, it depends on competent Writers and Directors both. Producers? Perhaps.
Alien, Aliens, Alien³- David Giler and Walter Hill, Ridley Scott- Dan O'Bannon & Ronald Shusett, James Cameron, David Fincher.
Full talent involved in each one.
AR- Jean-Pierre Jeunet and Joss Whedon.
AVP- Paul W.S Anderson and Shane Salerno.
AVPR- The "Strauss Bros" and Shane Salerno.
And that's to say nothing of Alan Ladd Junior, Gale Anne Hurd or Gordon Carroll.
Or the fantastic cast and crews for the first four. Film's a collaborative effort but you can usually ballpark it based upon who's working on it and their history; Neill Blomkamp has a history of writing his own scripts, badly.
