Not to watch. You’d like “Chainsaw” to be campy fun, but after a funny prom-night opener, you’re rooting for almost everyone to die. Zellweger’s a wallflower terrorized by the family from hell: Leatherface (Robert Jacks) dances with his chain saw while his demented brother Vilmer (McConaughey) stomps around on his mechanical leg. Then there’s more plot stuff that maybe the director can explain. McConaughey’s awful but clearly having a ball–frankly, you feel worse for him in “Contact”–and Zellweger is endearing when she finally tries to save her life. No force on earth, however, could have saved the movie.
