Why Are Batman Movies Afraid Of Robin?

As much as I absolutely love Batman, he is a ridiculous concept - but Robin is even more so. A grown man putting a literal child in mortal danger, night-in, night-out? It's one thing to accept that a billionaire with virtually unlimited resources, traumatised by the murder of his parents in front of him, is willing to take those risks himself; but happily putting an eleven-year old repeatedly in life-or-death situations goes against everything Batman is. No matter how well trained Robin is, he's a little boy against hardened career criminals. I know people say that for story purposes Robin's there to counterbalance Batman, to make sure he doesn't go too far or too dark, but that's simply solved by the writer. If Batman's written as fine on his own, he's fine on his own. No, I don't want Robin, and I'm both grateful and relieved he's been sidelined in the movies.

Because we're used to seeing Batman, Robin is a bigger novelty and would therefore draw more attention naturally - away from Batman and from the dark atmosphere of the world of Batman, venturing into a more goofy and camp vibe that most directors are trying to move away from. That's the main reason, I think.

Robin is like the shoehorned female character that serves no purpose and No one asked for.

I liked the way Nolan did it, making him the successor instead of a sidekick.

Robin is problematic. In the comics he is a kid, no one wants to have a kid in their movie and most of the more interesting plot lines are unfitting for a kid. So why would you need to try shoehorning him in? No, Robin works much better in a potential Teen Titan movie with a Batman Cameo (making the current Batman look older), so after both are established, they might team them up in the more interesting stories like when Joker kills Robin or how he becomes Nightwing etc.
So better to establish them separately, but always linked instead of teaming them up. So you can cater YA and Adults and build their heroes up.

Maybe the prime demographic of 16 to 35 year old males feel threatened by Robin? Therefore an intentional deletion of the character by the producers of Batman movies. Why do young men feel threatened by Robin? I don't see an air of irresponsibility by Batman in terms of putting Robin in harm's way as an answer. The most likely reason is they don't want to see a boy as it makes them feel like a boy. The whole self identification thing. Most non fans see the franchise as childish and Robin puts the exclamation point on that point. While we are at it most don't like to see Batgirl because that puts pressure on those who desire but lack a girlfriend usually not by choice. The dark universe tripe is just to muddy the water in terms of revealing self-inadequacy. Best to enjoy the franchise for what it is which is kicking butt of bad guys and not dig too far in for personal motivation as to fandom.

Robin's reliant on Batman

to actually answer the question, Robin was a character for the original TV show which was a lot less dark than the modern films? maybe his character just translates better to the original TV format than it does to the Hollywood Batman
