“Spectral” (** out of four) was a wearily derivative military action drama about a special-ops team (Bruce Greenwood, Emily Mortimer, James Badge Dale and others) that is dispatched to fight supernatural beings but soon find that they have their hands full and this will be a war to the death. Full of video-game like special effects, jingoistic speeches, and lots of gunplay. Watchable pastiche of “Starship Troopers”, “Alien”, “28 Days Later” and too many others to mention has enough firepower to make it watchable but a definite sense of deja-vu hangs over the proceedings.
