Were humans placed on Earth by extraterrestrials? That's the central question in this visually striking adventure, which brims with tension, intelligence and Alien-esque grossouts.
The year is 2093, and a group of explorers led by a corporate exec (Charlize Theron, captivating as ever) and a scientist (Noomi Rapace, equally superb) visit a distant star to look for the origins of man -- then get hunted by slimy monsters.

The 3-D flick looks breathtaking, with the planet feeling realistic. And the action pauses for some laughs, too, thanks to Michael Fassbender as a droll android.
Still, prepare for preposterous moments, even by sci-fi standards. (Would a scientist really swig booze while colleagues examine an alien nearby?)
Plus, horror cliches pop up occasionally, including a slain staffer who returns as a zombie. But mostly the thriller is smart -- and shocking. Just try not to close your eyes during the jaw-dropping scene involving Rapace, a slithery beast and an operating table!
