Countdown

"The topical nightmare has potential to get under your skin, but relies too much on familiar jump scares and easy violence."

"As proven by Mary Elizabeth Winstead in Final Destination 3 or the spunky Jessica Rothe in Happy Death Day, these fate-driven, high-concept horror flicks can be redeemed by a committed central performance. Countdown's Elizabeth Lail joins their company."

"This isn't a subtle, moody film filled with a sense of unease; instead, jump scares are around every corner. If that's all you want from a horror movie, you'll have a very good time - and an elevated heart rate for its speedy 90 minutes."

"The movie arrives at an eye-roll inducing final twist, and hints at an inevitable sequel. But this app isn't exactly begging for an upgrade."

"A pedestrian thriller whose personal-tech gimmick is even more thinly imagined than one might guess, it's a jumble of cheap jump scares made watchable by likable leads Elizabeth Lail and Jordan Calloway."

"Rather than screaming for them to go the other way, you'll be urging them to accept fate and die instead."

"[A] bombastically dumb new chiller that probably would have been called "Killer App" if that title hadn't already been used several times."
