"[It] is not funny, scary, exciting, interesting, or even a slasher. Watch something else (…) Rating: ★ (out of 5)" 

"[It] can’t quite live up to its name. A traditional slasher opening gives way to a lot of down time focusing on characters and story, neither of which are interesting or engaging, and both of which are continually absurd." 

"There's not much in there to make the movie worth recommending. But then we reach the moment slasher fans are waiting for, and Gauthier does something more interesting and unique than just having someone run around the park with a machete."
