Zathura is a 2005 family film starring Josh Hutcherson and Jonah Bobo as the young leads who play brothers and supporting them are Kristen Stewart (as the older sister), Tim Robbins (as Dad) and Dax Shepherd in a comic and serious role as an astronaut. It is an elaborate visual effects-laden game-based fantasy with a message for siblings about working together instead of apart (the parents are divorced and the brothers live with their father).
A game the younger brother finds in the basement somehow comes alive though this is not explained. When playing the game, the house is uprooted, and the brothers are surprised to find they are in deep space. To get back home they aim to keep on playing the game to the end, but they encounter a series of obstacles. For very young children some scenes may be too scary. For this reviewer it was all a bit of a drag. My rating: off-putting.
My response: Lukewarm. Experience negative, virtue positive.
