10,000 BC is the latest triumph of the ersatz from writer-director Roland Emmerich. Like Stargate (1994), Independence Day (1996), and The Day After Tomorrow (2004) before it, it's shamelessly cobbled together out of every movie Emmerich can remember to pilfer from (though to be fair, the section in pre-ancient Egypt harks back to his own Stargate). Emmerich's saving grace is that his films' cheesiness is so flagrant, his narratives so geared for instant gratification, he can seem like a kid simultaneously improvising and acting out a story in his backyard: "P'tend there's this alien ... p'tend maybe he came from Atlantis or something...." Just don't p'tend it has anything to do with real moviemaking. --Richard T. Jameson
