It took a leap of faith to go see “2012” on Friday the 13th. Watching the apocalypse is bad enough ... having an accident on the way home would be the icing on the cake. But I went anyway, a bit reluctant about watching director Roland Emmerich end the world ... again. What is it with this guy? He was probably the kind of kid who liked to break his toy trucks in the sandbox when he was growing up in West Germany before heading to Hollywood to make super hits like “Independence Day,” “The Day After Tomorrow,” “Godzilla” and “10,000 B.C.” Although Emmerich is a high-profile supporter of causes, from the rights of women, gays and lesbians, to global warming, about every five years he gets this irresistible urge to destroy the world. His weapons of choice are tidal waves and natural disasters, but he usually finds room for a mushroom cloud or two.
