Those are the only films that make real money. There was a time even during my life where could make a movie like the English Patient and net $200mm. That just doesn't happen now. There are too many other places to get that type of content, and people prefer to do so at home. So, yes, they still make them (I know that was rhetorical), but they don't generate mass publicity. That is reserved for GoT, etc. The formula now is to spend a lot to make a lot. Comics were ideal because the source material was already written and their demographic transcends pretty much anything. Rich, poor, any race, male/female...lots of people read them, know them, or at least think they're fun. Kids, adults, seniors. Even films that tank like Justice League still make money, but now we've seen what happens when they do it right with Avengers. The comic renaissance is more or less saving cinema, for now anyway. Theaters were in very, very serious peril before these started being made. They still are, but it's a slower bleed.
