Suffice to say Tragedy Girls has great fun with myriad horror movie tropes.

Funny, gut-churning, playful, wicked, and warm, Tragedy Girls is one of the better horror-comedies in recent memory.

The film’s young slashers are irredeemably smug and obnoxious, and their bloodthirsty craving for social media likes, represented by heart icons that float out of their cellphones after each murder that they document — without implicating themselves — fuels a vicious satire.

If Scream and Heathers shacked up and had murderous, millennial offspring, it might look a lot like Tragedy Girls.

The movie’s central idea and bright young cast are so good that some of its shallowness is forgivable.
