“7500” (**1/2 out of four) was an adequate but uninspired melodrama about a young pilot (Joseph Gordon Levitt) whose airplane is hijacked by terrorists (Omid Memar, Passar Hariky, and others) and he has to try to simultaneously survive the night, mantain his plane, and reason with the terrorists onboard so they don’t kill his crew. Nailbiting story is given a strong boost by Levitt who is fine as usual; unfortunately story never fully detonates and becomes too lumpy as it meanders towards its unsatisfying climax. Same story told more powerfully and with more cinema-verite effect in Paul Greengrass’ “United 93.”
