“Gifted” (*** out of four) was an affecting and effective melodrama about a single blue-collar parent (Chris Evans) raising his child prodigy niece (McKenna Grace) but problems begin to develop when he is drawn into a wrenching custody battle with his mother (Lindsay Duncan). Evans, as the beleaguered and conflicted dad, has never been better and Grace matches him in a first-rate performance as a child genius who still has a lot of emotional development to make and they both have a lot of tearjerking moments in the second half. Only the mawkish ending doesn’t ring entirely true. Beautifully shot by Stuart Dryburgh.
