Why do people say it's "too early" for Robin to be introduced in the Batman 2?

Wasn't Robin/Dick Grayson introduced fairly early in the series/comics? Plus you can't have Batman without Robin? Dick Grayson is the OG Robin and he's pretty essential to the story and Batman's character since it has not be a superhero but a father figure. Batman having a family in general is important to his character.
