movie could have been good

i really liked it for its subtleness...i mean we never saqw the daughter do the crabwalk, and though she did throw up it was realistic she wasnt just projecticle puking all over people randomly...we never see her actually attack anyone, the slow mpace never seeing the creepy (who actually were kind of creepy) monsters until the end, the lack of music telling you how to fell...the film reminded me of a better versin of the jessica chastain letdown mama mixed with something of m night shalayman...what messed up for me was the end. the little brother represented hope and was really the only thing holding the characters together...i think they should hav made him and his father survive...but i felt like the movie was different than others...it had a quality that made it much more watchable....and did i hate the dead animnal parts absolutely..so that is saying something
