..it's kids causing a lot of trouble because they won't listen.
Other than that.. I would've rated this movie an 8 if it weren't for the 2nd part of the movie. The end of the movie takes forever and it seems they had to sacrifice at least one of the cast to make it not that perfect story where everyone survives. I'm not the writer of the movie. I'm not a writer in any way, but I think I could do better.
By reading the comments, I really need to see The Wave I guess..
