This is a smart film adaptation of the illustrated serial novel by author Holly Black and artist Tony DiTerlizzi, which was as much concerned with reproducing the ‘field guide’ to goblins and fairies that serves as the mcguffin as telling its fairly straight-ahead kids-and-magical-creatures storyline. Mom (Mary-Louise Parker) moves to a small town after a painful split from Dad, and has a struggle maintaining a connection with the variously troublesome kids. Set-ups like this recur in contemporary kid’s stories, and this is as absent-father-centered as a wearisome number of recent American films — though the divorce mostly provides a modern spin on the plot devices which semi-orphan young protagonists in the likes of The Railway Children or The Lion, the Witch and the Wardrobe so they can be left to their own devices to have adventures. The kids are twin boys, resentful Jared and passive Simon (Freddie Highmore), and their slightly older sister, aggressive fencer Mallory (Sarah Bolger) – but the lead is Jared, who still hopes his father (Andrew McCarthy) will rescue him from the ‘Addams Family’ house Mom has stuck him with (Dad hasn’t yet had the guts to tell him he’s moved in with another woman) and grates on both his siblings in different ways. Jared comes across the eponymous book, compiled by the long-missing Arthur Spiderwick (David Strathairn), which contains many secrets about the various supernatural denizens that lurk mostly unseen about the property, but can’t cross a magic toadstool line of protection about the house.
