To a little piggy bank in Box Office Heaven we like to call February. Four new candidates to rape you of your hard earned cash this week, including the romantic comedy spoof “Date Movie,” a movie that is apparently so bad that it wasn’t even screened for critics, the kidnapping thriller “Freedomland” that might as well have been called “The Forgotten 2: We Forgot We Already Made This Movie,” and the Disney based-on-true-events snow dog film, “Eight Below.” Sigh. The one glimmering hope of entertainment this weekend is in the semi-limited release of “Night Watch,” the first part of a Russian fantasy film that’s being hailed as Eastern Europe’s “Lord of the Rings.” A pretty hefty statement, but one that I’m excited to see nonetheless.
