“Dune Drifter” (**1/2 out of four) was a moderately engaging sci/fi action thriller about the survivor (Phoebe Sparrow) of a devastating orbital space battle who crashlands on a desolate planet and must survive against otherworldly creatures and fend for herself before her life support expires. Well-produced and overall well-done on a slender budget, with some stylish visual effects and cinematography, but hampered by its overall derivation of other sci/fi classics such as “Dune” (if you couldn’t guess from its title”) and also “Alien” and “Stargate.” Still, though, better than most direct-to-DVD trifle.
