A little heavy on the guess-who and I'm sad that the mouse is gone. It was okay. I only remembered bits and pieces from the books but it seems like they captured it pretty well.
I'd consider these films to watch with the kids.
Surprisingly this was quite bad. The editing in the action sequences lacks continuity and a sense of 3d space. At one point the henchman eats a carrot. It is the only vegetable in the film, yet it is not explained.
Willis is perhaps only one sequel from vegetable himself. He spends most of his time yelling inappropriately, often to himself, and is out of touch with what's going on.
A beautiful piece of work, superbly acted and directed. I really enjoy Gondry. But I found myself a little bored and distracted here. After you suspect and then realise the film's conceit, the director is still typically self-indulgent before bringing you to the end.
The Black Cauldron is quite scary for a kids' film. From my memories of the books, it's also a poor adaptation. It's often quite unclear what's happening and once everything breaks loose it's all wrapped up unexpectedly quickly.
As much as you were considering watching this… don't.
