As with his A Christmas Carol movie, Zemeckis paints himself into a digital corner by ignoring adults.
It's only the occasional unnatural look of the motion-capture animation that is still a stumbling block for producer Robert Zemeckis and the team that created "The Polar Express" and "A Christmas Carol."
The point of "performance capture animation " – the expensive process by which live actors are turned into semi-animated characters – entirely escapes me and is no more interesting here than in The Polar Express or Disney's A Christmas Carol, Robert Zemeckis's earlier uses of the technique.
In "The Polar Express," "Monster House," "Beowulf," "A Christmas Carol" and now "Mars Needs Moms," Zemeckis — also responsible for such cutting-edge special-effects films as "Forrest Gump" and "Who Framed Roger Rabbit" — has pursued an apparently keen interest in "performance capture" or "motion capture" filmmaking, in which actors are photographed while covered in reflective markers, so their movements and expressions can be electronically tracked and then translated into computer-generated imagery, to create animated characters.
The results, as seen in Zemeckis’s previous mo-cap features A Christmas Carol, Beowulf and The Polar Express, can charitably be described as interesting, but they’re considerably short of enchanting.
Much like “The Polar Express” and “A Christmas Carol” before it, the Zemeckis-produced “Mars” fails to deliver emotional and comedic blows thanks to the dead-eyed mannequins standing in for characters.
