What a waste of two hours. I think the ending has been covered in enough detail. I won’t go into to that.
However, I will share my thoughts on the two absolutely USELESS daughters. Neither one had any affect on the advancement of the plot. At least the brother got sick, and required his dad to go get him some help, which ultimately showed how unprepared he was for what was happening. One daughter was a pot smoking wise-arse who spewed negativity every time she spoke. The other saw some deer, ran away, and chowed down on junk food.
The movie would have been exponentially better without their distractions.
This movie had a strong M. Night Shyamalan feel. But, lacked the caliber of his direction.
One positive effect the movie did have one me, was bringing back the Kevin Bacon game.
