Scott was not working during the Classic Hollywood era- so no Hayes Code or Studio System
so he had so much more control over how his films looked
he presents themes that run through his works which include: heroines, artificial intelliigence/technology, class conciousness, and the relationship between humanity and a hostile universe
his visual style includes things that are experimental such as: his cinematography, use of colour and light, dynamic storytelling ( not just narrating events, but combining many things to create connections).
he's also quite adventurous in his storytelling style, often using unconventional structures
he's known for being quite in control of lots of elements of production
