M3gan
A woman has to take care of her Niece after her Parents died and as she is a Toy Creator, she gives her a prototype life like Doll who becomes a Killer (Chucky style)
A bit slow at the beginning but it does pick up rather nicely once, M3gan starts to become more evolved and starts murdering people and she can get creepy.
As a previous Reviewer said, there is more gore to this Film (I think we will see an Extended Edition upon DVD/Blu-Ray Release)
There will be a Sequel,
