I love Shark-movies, because they're still horrormovies, but I don't get any nightmares..so they're great..If you wanne see Sharks and feel the adrenaline, the movie is perfect for you..unfortunately the Meg hasn't the best backstory and the whole movie isn't really realistic...for me the adrenaline is enough..but I don't think, that everyone can say that about his or herself...
