Nice but not 7.7

Rating: 6/10 (3 August 2018)

Plot full of holes..

all the inventors , us army and scientist never found a solution for those creatures ??!!
if the sound of the river covers human sounds so why they didn't make some noise near the house and solve this problem for good ??
how the F* that f* nail placed in the middle of the stair ??
if the kids were drowning in the corn how did they put the iron door over them in the hermitage ??

there's no characters development .. no scenario or plot but no one can deny that is good thriller and it's entertainment movie but definitely not worth 7.7
