This is a very interesting lesson. I watched this movie on Netflix a time ago and i was very shocked and surprised. First you see Blake Lively like a superficial girl, but when she goes inside the sea and fight with a shark, you get very inspired by her courage. I was thinking what’s wrong with this shark, why he is so agressive, he is not letting her go… It did not settle down till the limit where he could kill her. He killed three other people who tried helped her, but he was unsuccessful because in the end you discover that God sent her to kill the shark. Be strong, be bold, never give up.
