Halloween weekend we can choose between tween vampires (Let Me In), alien invasions (Monsters), evil spirits (Paranormal Activity 2), or sick minds (Saw 3D). I’m crazy over the first choice, excited to see the 2nd, curious about the 3rd, and wish the 4th option would go away. Or we can stay home October 31 and watch the premiere of AMC’s new zombie series, Walking Dead, directed by Frank Darabont.
