Listen, Son, to what I have to say about comprehensible input. It's not something new you need to learn; you've used it in the past.

When you needed to learn Dutch after your family moved there, you did that through reading Ot en Sien and Kruimeltje. Later, when the folks returned to New Zealand and you needed to switch back to English, you read Superman comics, the Famous Five and you scoured the Children's Library shelves labelled Myths and Legends from Many Lands.

That's how you got yourself comprehensible input - by hunting down  interesting material at your level.

It’s possible thereafter to expand the difficulty limit of the material if you have a way to making it understandable (i.e. cheating is allowed.)

If you already know the story, that’s good (unless you are disinclined to re-read books or watch movies again and again). But you could get around that by seeking more by the same author, or by continuing in that genre.

If your listening is at a level where it supplements your understanding, then listen to the audiobook at the same time as you follow along on paper or the screen.

And if you read on screen, you might use an application that gives you the meaning of words when you scroll over them.

 
Yes, there are always means and ways.
