I agree, and Blade Runner is very dated (80s fashion and music). Alien on the other hand hasn’t aged a bit, and along 2001 and Star Wars really defined scifi movies. The same guy reinvented peplums with Gladiator, and war movies with Black Hawk Down. I think it’s enough to justify all the misses.
You can download IMDB’s database as flat files. It is interesting to see the evolution of imdb ratings over a director’s career. Some are remarkably stable like Woody Allen or Martin Scorsese. Some others falter like Brian de Palma. Ridley Scott has some ups and down but is fairly stable over a long career.
From my experience all atmospheric films are like this. Some people love them, some people find them boring because they are more about visuals/sounds/music/feelings rather than plot lines or action scenes.
Blade Runner was an ambitious, pretty, ambient but also boring film. To refer to it as the GOAT is hyperbolic. To call Scott a genius etc. because of Blade Runner is also unjustified because all its strengths trace directly to PKD, Syd Mead, Jordan Cronenweth etc.
It's one seriously overhyped film. All subjective of course, but then so are such articles and they arguably add to the hype.
