You seem to be making my original point for me with the latter stuff, the negative reaction to Blade Runner pushed Scott much more towards a commercial mindset for his latter career.
Early Ridley Scott I would say did very clearly have a signature visual style, arguably THE most influential visual style of the last 40+ years(albeit with obvious influence from the likes of Kurbick and Tarkovsky plus classic noir on him) and even in his latter years his film carry some of that, for Alien and the Duelists he was actually doing most of the camera operation I believe. Writing wise I think he could actually have claimed a story credit for both Alien and Blade Runner but chose not to, you listen to People's especially talk about writing and its clear Scott is providing a lot of creative input
