Apparitions
 

If you haven't seen the BBC show Apparitions, I recommend you give it a go. It's a very fun and well-made six-episode series about a Catholic exorcist. Great atmosphere (especially if you like church/exorcism stuff), top-notch acting, smart scripts, some scary moments. It might be hard to find -- last I checked, it wasn't on Netflix or Amazon -- but it's worth the search.

Enjoy!
