First, leave your morality in the house then you can watch it. Its morally wrong on so many levels but it's a movie, don't forget that.
Second, If you are a male who wants to feel super adrenelin rush for continuous 3 hours and have a bit of raw emotion, then you can watch it
Last, Watch it in the theatre and feel the amazing scores throughout the movie.
If you are someone who check their phone is between the movie, it's not for you then.
