Worst shark movie I've ever seen. Every scenario could have been avoided and everyone besides the 1st victim could have been saved. The handyman has a vehicle and they could have all left right at the beginning.
Even if they hadn't escaped in the beginning they could have just gone upstairs and then to the roof, even grandpa, and lived. The water never would have topped the roof.
Oh, and the 16 yr old boy? He was so cowardly that he let his grandpa die rather than grab him and pull him up the stairs, plus let his sister "distract" the shark first but then at the end could out swim the shark?
This movie even had to use CGI rain, really?
