I'm someone who loves horror movies. This movie was like horror pro max. Took it to the next level. The concept was new to me & the short description was overwhelming. First half was so smooth, I have started guessing with my horror instinct, probably some rogues must have followed them to the mall and torture them whole night.. or some usual ghost pranking within the closed doors..But old cranky couple was way out of my expectation. Scenes after the old couple entry was like God.. for a moment my beats increased like anything. On a serious note, I'm not gonna suggest this movie for not even an avid-horror movie fan.
