“They’re Inside” (*1/2 out of four) was a gruesome horror show in which two sisters (Karli Hall and Amanda Kathleen Ward) go to a cabin in the woods to put together a homemade film when two masked strangers show up and attempt to film them being tortured and killed. Hard to believe that two new horror movies in the same week could rip-off the same movie (“The Strangers”) but seeing is unfortunately believing. Film doesn’t so much end as stop but believe me no one will be complaining.
