“Puppet Master: Doktor Death” (* out of four) was a dreadful entry in this inexplicably popular and endless series about the return of the return of the title murderer who pops up at a senior-care facility involving various nurses and patients (Melissa Moore, Rick Montgomery Jr, Laura Dennis, and others) and mayhem ensues. Unfortunately, the puppet itself is the best actor and performance here because most other performances and filmmaking are painful. Horror fans would best watch a “Muppets” re-run for more scares and more laughs. Someone please put this series to “death” before more sequels are made.
