“The Card Counter” (** out of four) was an oddly bland melodrama about a former military investigator (Oscar Isaacs) who is released from prison and starts a new career for himself as a gambler and card counter and soon sees where this new life takes him as he falls in love with a fellow high-roller (Tiffany Haddish). Typically moody outing from writer/director Paul Schrader (“Taxi Driver”) but never catches fire and is weakened by lack of substantial storyline. Even the usually strong Isaacs seems muted; Haddish is first-rate, though, in a real change-of-pace role and her scenes with Isaacs are the only time the film hits the jackpot. Similar story was told in Robert Redford/Sydney Pollack’s 1990 “Havana.”
