“Geostorm” (** out of four) was an unexceptional disaster thriller about a scientist (Gerard Butler) and his estranged brother (Jim Sturgess) who realize it’s apocalypse now and race against the clock to save Earth when the network of satellites designed to control the global climate begin to attack creating massive destruction. Serviceable action thriller liberally rips off “The Day After Tomorrow” and “Armaggedon”. Second half offers some flashy visual effects and action scenes but movie still feels unnecessary and hollow. Top-notch supporting cast including Ed Harris, Andy Garcia, and Abby Cornish are mostly wasted. Inauspicious directing debut for Dean Devlin who was one-half the creating team behind “Independence Day” which come to think of it, is another movie this rips off.
