Jessica Rothe plays a luckless heroine in this cheekily entertaining horror movie.

Imagine Groundhog Day remade as a slasher thriller and you have a rough idea of what’s in store for sorority mean girl Rothe. She finds herself reliving her birthday over and over again, a day that always ends with her meeting her demise at the hands of a killer in a creepy baby mask.

Only by discovering the identity of her mysterious assailant, it appears, can she end the cycle and survive.

Like Bill Murray’s cynical TV weatherman, Rothe’s birthday girl is not that likeable at first, and much of the movie’s fun is seeing her become a better person as she goes through her ordeals of being stabbed, brained, drowned and blown up.
