This season seems a bit overstuffed, doesn't it? As if aliens and seemingly immortal serial killers weren't enough, they had to add demonic possession and zombies. What's next? Witches, vampires and werewolves? Frankenstein's monster and the mummy? Scary Clowns?
I think I preferred it when they stuck to just one major supernatural element (ghosts) in season 1. Oh well, I guess it's still kind of fun, crazy as it is.
