It's so hard to pick favorites. There's no shame in loving the classics but what about our favorite B movies? Would my Mania membership be revoked if I admitted to multiple viewings of "Big Man on Campus" or "If Looks Could Kill"? My personal tastes are indefensible. These movies are endearing to me because of personal experiences and I wouldn't expect anyone else to love them the way that I do.
That being said, I love sci-fi and fantasy in general. I also love "true" tales of the paranormal. I love when the fiction and "non-fiction" cross over and influence each other as authors strive to find source material and witnesses grasp to explain their sightings.
