Logan Marshall-Green, Noopi Rapace, and Michael Fassbender in PrometheusPROMETHEUS

After many months of speculation, the question of whether Ridley Scott's Prometheus is, in fact, a prequel to the director's Alien can finally be answered: Hell yeah it is. And a good thing, too, because the enticing echoes of that 1979 sci-fi/horror essential are among the scant few elements that truly resonate in this visually extraordinary but only fitfully engaging endeavor.

Kevin Spacey and Jim Sturgess in 2121

Based on the Ben Mezrich nonfiction Bringing Down the House: The Inside Story of Six MIT Students Who Took Vegas for Millions, the film 21 boasts a far snappier title, yet I wouldn't recommend viewing it if you're even a day older than that. It's not often that a true story is re-told with such aggressive fraudulence, but 21 is a rare and rather spectacular failure - one in which your bullshit detectors wail at you early on and don't stop until you're rendered nearly deaf. The movie is directed by Robert Luketic, who also helmed Legally Blonde, and it's all just slightly less believable than Legally Blonde.
