“Fifty Shades Darker” (** out of four) was a tepid second chapter in the twisted and erotic love story between billionaire Christian Grey (Jamie Dornan) and a literature editor (Dakota Johnson) as their relationships deepens from sex into love. A definite improvement over the laughable original but this is still pointless and meandering at times. Dornan comes off much better than the original and Johnson is stirring but they still fail to ignite as an onscreen couple. Well-directed by James Foley although this is a long way from “Glengarry Glen Ross.”
