Todd Gilchrist editor There are very few movie genres in which Emma Thompson hasn’t left her mark, but she’s established a special pedigree in romantic comedies: from “The Tall Guy” to “Sense and Sensibility” to “Love Actually” to “Good Luck to You, Leo Grande,” she’s explored love in more ways on screen than most people get to experience in real life. In the romantic entanglements of writer-producer Jemima Khan’s “What’s Love Got to Do With It?,” Thompson’s more of a well-meaning instigator than an active participant, playing a divorcee named Cath who clumsily tries to make a match for her serially-single filmmaker daughter Zoe, played by Lily James. Zoe, meanwhile, is more interested in documenting the arranged (or “assisted,” they rebrand it) marriage agreed to by her childhood friend Kazim (Shazad Latif), not realizing the complicated feelings that his impending nuptials are igniting in her about relationships past, present and future.
