This Halloween, if you want to give yourself a good scare, you've got options. You can get down with AMC's flesh-eating 'The Walking Dead' on Sunday, or take in the Canadian debut of 'American Horror Story' on brand-new FX Canada channel on Monday, but for my money, the most genuine chills to be had are over on Space (Mondays at 10PM), with 'Paranormal Witness.'

Quietly growing its audience from week to week, this reality series is surprisingly effective considering the tools in its arsenal are pretty familiar. It retells scary and unexplained stories using a mixture of reenactments, interviews with actual people, archival audio and video and lots of spooky sound and lighting effects. So basically, things 'America's Most Wanted' wasn't doing. But the show transcends the sum of its parts, and I think it comes down to great writing and great casting.
