Movies can influence us a lot more than we think. Watching movies should be beyond just for the purpose of seeking entertainment. It can affect us either positively or negatively is we are not careful.
What we allow ourselves to be consumed with have a way of affecting our choices in life. We are products of what we continuously consume. It's not only applicable to food, it also extends to things we see and hear.
The most important reason for going through a movie is for the purpose of what we stand to gain at the end of the movie. We must bear in mind that not everything we watch builds us up spiritually.
If we are not careful we may see ourselves gradually changing because of what we have allowed our eyes to be fed with. Movies were originally intended for the purpose of instilling morals on the viewers, but the kind of movies we see presently a lot of them so the opposite. This is why it is important for us to carefully decide on which movies we see and the ones we avoid.
