LA LA LAND's pretty darn entertaining. Who'd've ever thought Hollywood could get America to love Bollywood. Ingenious. But I think it deserves special note for its unassailably politically correct sensitivity to every sort and sub sort of diversity anyone could conceive of and Casting could supply. About half way through, I started imagining a small army of assistant directors behind the scenery during every crowd scene, waiting to pounce onto the sets between takes to make sure that no other heterosexual, mono-racial couple except the two stars was anywhere near pulling focus. OK, Hollywood, we get it. Now what? Is everybody happy?
