PlanesPLANES and PERCY JACKSON: SEA OF MONSTERS

From a grown-up's perspective, I guess that as far as family entertainment at the cineplex goes, Disney's animated Planes and the mythology adventure Percy Jackson: Sea of Monsters could both be considered "harmless." But can you really apply that adjective when something, in both movies, is indeed being killed - namely, your time?

In the third cinematic installment of C.S. Lewis' Narnia series, the cumbersomely titled The Chronicles of Narnia: The Voyage of the Dawn Treader, we're introduced to a character new to the franchise - a grouchy little snot named Eustace Scrubb. The pre-adolescent cousin to the young heroes of 2005's The Lion, the Witch, & the Wardrobe and 2008's Prince Caspian, this kid, played by Will Poulter, is truly a piece of work - closed-minded, miserly, cowardly, and prone to explosively motor-mouthed bouts of hysteria. With his constantly knit brow and the voice of an aggrieved, middle-aged schoolmarm, Poulter's Eustace is about the most obnoxious, potentially alienating figure that you could ever imagine popping into this fantasy saga. He's also so side-splittingly funny that he almost singlehandedly makes Dawn Treader not just enjoyable, but easily the most surprising screen Narnia to date.
