The issue is this: movies are expensive to make, and ticket prices keep increasing. The investment in a film is so immense, that producers get nervous on anything new or different. They worry that the movie won't find an audience, that the concept won't draw enough money to make back their money. So they lean toward properties that people recognize. It's easier to market a film with a familiar name or character, so they look for familiar names and characters. Audience look at the cost of a ticket and also want assurance they'll like it. If they recognize the franchise/remake, they know what they're getting for their money. So the two trends dovetail. Also, audiences want spectacle. If you're paying $15 a ticket, you don't want to see a movie without it. Small dramas can play out on TV, but people want something for their money that doesn't come across on TV. So spectacle it is, and when it comes connected with a known name, financing falls into place. And if you can't provide the spectacle, a known quantity is easier to finance and sell. I've seen this trend occur in other art forms: as cost and prices rise, people are unwilling to risk money on something unknown.
