After dispensing with a few space-jockey clichés, the movie focuses on a Mars-bound rescue mission commanded by Jim McConnell (Gary Sinise), whose team (Tim Robbins, Connie Nielsen, Jerry O'Connell) has been sent to retrieve the sole survivor (Don Cheadle) of a tragic Mars landing. During the sequence en route to Mars, De Palma's in his element with two suspenseful scenes (including a dramatic--albeit somewhat silly--space walk) that are technically impressive. But when this Mission gets to Mars, the movie grows increasingly unconvincing, finally arriving at an alien encounter that more closely resembles an astronomical CGI video game. But this is a $75 million Hollywood movie, and no amount of technical wizardry can lift the burden of a juvenile screenplay. Kudos to Sinise, his costars, and the special effects wizards for making the most of hoary material; shame on just about everyone else involved. --Jeff Shannon
