Tragedy Girls (3.5 stars) - Brianna Hildebrand (Deadpool) and Alexandra Shipp (X-Men: Apocalypse) star as a pair teen besties who run an online site fixated on death, but long to create a story of their own that capitalizes on the buzz of their outlet. Their scheme: lure local serial killer (Kevin Durand of The Strain) into a trap, imprison him, go on a killing spree and pin everything on him. Seems clever enough, but what fun would this movie be if it all worked out? Tragedy Girls is a playful, comical and deliciously wicked splatter-fest that’s best described as a bloody cocktail mix of Mean Girls and Scream. Even with all its tie-ins with modern culture and social media obsession, the horror elements are very much alive. Audiences will eat it up. Rated R, 98 minutes. At the Alamo Drafthouse Cedars in Dallas.
