Doll Graveyard (2005)

When Sophie breaks a vase, her abusive father forces her to dig a grave for her dolls in the backyard.  As she is climbing out of the hole, she slips and falls backwards into it.  Rather than seeing if she is okay, her father buries her with the dolls to cover up the accident. What a great dad.

Cut to current day, where a father and his two teenagers are living in the house.  The son, Guy, finds one of the dolls poking out of ground, and as he is an action figure collector, he cleans up the doll and displays it in his room.

While dad is out on his first date, DeeDee invites some girl friends over to drink and smoke pot.  Two overbearing jocks decide to crash the party and tie up Guy in the process.  Then the dolls go nuts and Sophia's spirit starts taking over Guy.  The teens are idiots as they continue to stay in the house after the killings start and neglect to call for help until several of them are already dead.

Another Charles Band movie in the tradition of the Puppet Master films - small dolls killing people with their small weapons.  The creepiest one is the doll with the jagged mouth, ick!
