Pixar veteran Andrew Stanton (Finding Nemo, WALL-E) adapts a series of novels by Edgar Rice Burroughs about the adventures of a Confederate soldier on Mars. The books offer enough material for several movies, which seems to be the root of the problem here: the movie is so overloaded with exposition that the situations have little room to develop. Unlike Stanton’s memorable animation features, this is surprisingly devoid of humor or winning characterization, though the special effects are fantastic. Novelist Michael Chabon worked on the script; with Taylor Kitsch and Samantha Morton.
