If you loved The Spiderwick Chronicles, try Magic Camp
A bridge between a film you've already seen and one most people haven't. Magic Camp has roughly 13.2× fewer votes than The Spiderwick Chronicles — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Mark Waters, and they sit in Family / Fantasy territory. If that's the register that drew you to The Spiderwick Chronicles, the second film will land in a comparable space — through a different lens.
What Magic Camp is
Magic Camp apparently thinks it can make magic happen. Andy returns to his childhood camp to help rookie magicians. It predictably finds a spark in them.
