“Grand Isle” (*1/2 out of four) was a leaden Southern Gothic melodrama about a handyman (Luke Benward) who is arrested for murder and has to prove his innocence by recounting what happened the night of his arrest involving a bizarre family (Nicholas Cage and Kadee Strickland) who he was working for. Director Stephen Campanelli infuses this with a heavy atmosphere but everything else about it is heavy as well, including Cage who more-or-less is playing the same character he did in “Con Air.” For a richer and more striking look at similar characters, watch 1987’s “Angel Heart” instead.
