4. Annabelle (2014)
She didn't have a whole lot to do in The Conjuring, but audiences were suitably intrigued by creepy old Annabelle, so she got not only her own spinoff movie, but also an upcoming sequel! Here we discover what made such an innocent-looking dolly turn into some sort of malevolent supernatural spirit. Suffice to say it involves a pregnant woman, a home invasion, and some Satanists. It's all fairly standard stuff, but considering it's a spinoff flick, Annabelle is actually pretty decent.
Where to watch it: Rental at iTunes, Amazon, Vudu, etc.
