In real life the actress playing the Mum 41 and the actress playing the daughter is 27 . I think sharks would only kill for food but the shark in this film is killing lots of people and not eating . Most American movie’s characters are always saying” I love you “ all the time , even if a character is just going to the toilet and they will see them in 4 minutes.I should say bathroom instead , because it’s rude to say toilet in America. Having said that there are some fantastic American movies and programmes and actors. I even like the actors in this movie and it was a good idea for a movie but it didn’t work as well.
