I don't get the hate on the storyline
Guess what... this movie wasn't supposed to have a storyline!!!
It was nothing but a feel good comedy. Grown up school buddies take their families on a retreat and everyone hangs around and has some fun together! That is it!
The movie didn't even hint at trying to show anything more than that. It was just about families spending some good times together!
Saying that this movie had a weak storyline completely misses the point of the movie!
