The game's visuals have an almost pop-up book quality that immediately gives a sense that The Spiderwick Chronicles isn't a typical movie tie-in. Rather than going for more traditional modeled characters or sprites, the visual style takes a cue from the illustrations seen in the book series. Everything looks like it was hand-drawn in black ink then touched up with watercolors. This not only makes it one of the more artistically beautiful games available on the system, but it helps it build a unique visual identity. Although the effect doesn't always carry through (some areas look sparse and there are bouts of repetition), it is still nice to see a licensed game break out of the norm.
Sound is kept low-key for the most part. The score is nice and complements the game's look and feel nicely, though it can sometimes drone on a little too long. Still, it has that magic quality most good game soundtracks exhibit - it stays out of the way and doesn't compete for your attention.
