“Solar Impact” (** out of four) was a not-bad horror thriller set in the not-too-distant future in which a group of friends (Grace Dixon, Oliver Goodwill, Polly Kilpatrick, and others) try to band together and survive a solar radiation disaster which has left the rest of humanity turning into flesh-eating zombies that are out for the apocalypse. Competently made and features some overall good acting and dialogue but ultimately too derivative of “World War Z” which in itself was a derivation of “Night Of The Living Dead” and “28 Days Later.” At this point, there may not be much left to do with movies about the apocalypse and about zombies anymore.
