Sooner rather than later, it was inevitable that we'd be treated to another helping of Doo. Just as predictably, nothing has changed.
The second big-screen Shaggy-and-dog story not only pits Mystery Inc. against another masked villain - albeit this time one with a monster-spewing device - but follows the first's sloppy paw-prints in nearly every way.
The screen is kept chock-full of cool-looking monsters, resurrected from the cartoon, and the giggle count climbs whenever Scoobs and Shaggy (Lillard) share yelping non-sequiturs.
Yet once again everything else falls flat, from the low-wattage guest appearance from Big Brovaz, to the stale character arcs given to Fred, Daphne and Velma. Themes of self-acceptance and inner strength seem a little out of place in a movie featuring a hound farting at phantasms.
