Remake = Hollywood creative bankruptcy, lack of original ideas.
I know that sounds a little silly seeing as to how much I love adaptations, comic book movies, sequels and everything. But most of these remakes these days are trash . . . and Clint Eastwood agrees with me. He called most modern remakes "nonsense".
The problem is not that no-one has any ideas. The problem is that new ideas are an economic risk, and Hollywood is constantly in pursuit of the "risk free" movie formula (which does not actually exist, but they think they can find it anyway). If an idea for a movie does not have some kind of built in audience-- that is, they know that
somewhere, people will already know what it is and they'll tell their friends about it. Hollywood does not like giving out 100 million dollar budgets to movies unless they're a sequel, remake, or adaptation, because they think that the only way to make back a 100 million dollar budget is with a so-called "pre-installed audience." If you are a huge name director it's not so bad though, because your name is what gives the movie its "pre-installed audience."
The problem is not that Hollywood is bankrupt of ideas; the problem is that they are terrified of taking risks. And unfortunately, he fact that no-one in hollywood is taking risks means that they are essentially cutting off industry growth, and just clinging to what they currently have. These days if a big movie flops, it hits the studio
hard, because that's one less franchise that they can potentially milk in the future with sequels. Eventually, Hollywood is going to run out of bankable IPs to mooch off of, and at that point they're either going to have to start spending on new ideas, or the movie industry is going to crumble.
The oddest part of all this though is that now, if you have an idea for a movie that you really want to pursue, your best bet is often to develop it as a novel or comic book first. It's easy enough to sell a script in Hollywood, but to actually get one made into a movie is ridiculously difficult due to Hollywood's current mistrust of originality. Basically, the only real way for new IPs to have a chance is to trick the studios via a Trojan horse, be it a comic book, novel, or video game.
