“Texas Chainsaw 3D” brings one interesting new facet to the nearly 40-year-old franchise — and it’s not the half-hearted 3D, which adds up to little more than the occasional shot of the titular implement bursting out of the screen. What the movie does do, which horror buffs may or may not go for, is turn the terrifying, bloodthirsty Leatherface into a maligned and misunderstood monster.
He doesn’t throw daisies into a lake with a little girl, mind you, but we’re still meant to feel his pain and to side with him against the local redneck vigilantes who have hounded him and his kinfolk. Beyond that curveball, however, “Texas Chainsaw 3D” is a dreary slog through the dreadfully familiar. You’ve seen it all in a million movies: attractive victims doing stupid things, foreboding secret passages, bifurcated corpses.
