Sandwiched among the usual superheroes and science-fiction epics comes a very odd summer tentpole release, an extravagant, big budget adaptation of F. Scott Fitzgerald’s literary masterpiece, “The Great Gatsby,” directed by Baz Luhrmann (“Moulin Rouge!”, “Romeo + Juliet”) and in 3-D. Just like that description, the film itself provokes extreme ambivalence. Luhrmann has a distinct style people either love or hate. I’m in the latter category, and “Gatsby” did nothing to change that.
