My advice to the parents that pleases avoid such movies for your childrens better future.
As per my view Mastizaade film affect the life of small school children learning at the age of 14 to17 because this film contain double meaning words and some dirty seen which give rise to see unwanted vedios which children should not see and even effect on studies. If students mind is diverted from studies to such movies it mainly effect on their board exams so my humble advise is that school students should avoid such types of movies.
