The ship so nice they sank it twice, only this time, with a 3-D up-charge. James Cameron’s 1997 film returns for the 100th anniversary of the doomed vessel’s 1912 voyage. The 3-D is pretty good, but still a straight-up postproduction conversion job. Eh. But Leonardo DiCaprio and Kate Winslet are back (ah, so young) with all their eye-roll-worthy dialogue. At least Cameron is a genius at instilling narrative dread and providing incredible cinematic images. The show will, you know, go on.
