Is M. *beep* Shyamalans' THE VISIT 2015 a copy of this?

Looks like old M. $hite Shyamalan copied someones elses movie AGAIN!

The Visit 2015 was pretty poor compared to this!

Lots of haters for this movie but it was pretty good imho - really twisted sister lol

My question would be how did the brother come to be there as well - a bit coincidental unless he came to find his sister and was grabbed by the same psychos - still a bit far fetched but its only a movie and it added to the sick twisted plot somewhat!
