Superhero movies are a hot ticket right now, with even the mediocre one earning millions of dollars at the box office. It's safe to say that most people enjoy comic book movies, but everyone has their own taste. In the case of acclaimed director Ridley Scott, he's not too big a fan of superheroes or cinema as it is in general. This is what director of Alien and Blade Runner had to say about the hottest genre in Hollywood.
Superhero movies are not my kind of thing -- that's why I've never really done one. [I've been asked] several times, but I can't believe in the thin, gossamer tight-rope of the non-reality of the situation of the superhero. I've done that kind of movie -- Blade Runner really is a comic strip when you think about it, it's a dark story told in an unreal world. You could almost put Batman or Superman in that world, that atmosphere, except I'd have a fucking good story, as opposed to no story!
I think you could put Batman in just about any movie and it would improve vastly, but that's just me. Ridley Scott shared his opinion on comic book movies with Digital Spy, telling the outlet that he really has no interest in them -- despite apparently being asked to direct them multiple times. It seems like he's not a fan of the unrealistic situations that are inherent in superhero comics. That strikes me as a bit of a silly reason to dislike them (there are plenty of other reasons out there), but different strokes for different blokes.
You might be quick to point out that some of Ridley Scott's most popular films, namely Blade Runner and Alien, aren't very realistic either, but I think the point he is trying to make is that those films at least exist in some realm of believability, either in the world or with the people. It's not a stretch to say that one day we will have commercial spaceships and meet deadly creatures or that corporations become more powerful than the government; it's harder to believe that we can get dosed in gamma radiation, turn into giant green rage monsters, and then go fight crime. At least with Ridley Scott's sci-fi films, you can track the logic of the choices the characters are making... Prometheus excluded.
