Likely the last time LAT film critic Kenneth Turan was on your radar came in 1998, when Turan's pan of Titanic was so against the grain that James Cameron himself wrote a letter to the newspaper calling for Turan's "impeachment." (This, of course, was before a decade of critical backlash against the film set in.) It may surprise you, then, that Cameron's bête noire just gave Avatar a rave, writing, "Think of Avatar as The Jazz Singer of 3-D filmmaking." Impeachment off! Four more years! [LAT]
