I get what you're saying, but there are so many fantasy novels where you're asked to step into another world.
They didn't reduce the number of synths in Humans, or decide that really people would only get the Hobbits if they were human sized, or think that people couldn't understand why they were killing children in death games in Panem.
Adaptations have to take a bit of licence, but the human-daemon relationship is fundamental to the story they're telling. Pan and Lyra just sat next to each other when Mrs Coulter's daemon had attacked him. They should have been cuddling and soothing each other.
That isn't just 'the scene was too crowded'. It's a fundamental error.
And this is THEIR JOB to execute the story effectively on screen. Yes, they can make changes, but they're neglecting the narrative in the process.
