Doom: the movie reviewed

The year is 2026 and the Union Aerospace Corp (UAC) has got a freaky problem on Mars on their hands and it's up to the Rapid Response Tactical Squad (pronounced "rrrrrrrrrrttss") to clean up the mess. Enter dynamic crew of contrasting characters, headed by Sarge, played by The Rock. They rush to Mars with almost-too-huge guns in hand via the Ark, a high-tech blob of floating mercury that tosses your cells to Mars so fast that it makes you puke. They hook up with a sexy scientist determined to preserve their research and then get the blasty show on the road, hitting the archeologists' dig site, some labs with floating grossness, and other familiar territory.
