When it comes to reviews grown ups 2 was not done justice. The reviews would lead people to believe that it is a terrible film but in reality it is amazing, it's a comedy the purpose of this film is to make you laugh and it does exactly that, people over analysed this film and found problems that didn't exist. So in my opinion don't read or look at any ratings before watching a film because they give you this false pretence in your mind which may ruin your experience look at reviews afterwards if you want.
