Movies definitely have a detrimental effect....
Even totally "Clean" movies advocate foreign values, In a way that it comes across as the Norm.... It has a subconscious effect.....
Also I find that to keep you interested, the movies are designed in a way that keeps you continuously expecting..... expecting to feel a sense of identity with the characters... or exposure to-the/of-the characters.... Usually the female ones
....
And once the movie is over (and the producer got what he/she needed from you i.e. to hang on till the end...) It leaves you hanging....
It almost never fulfills the expectation that it aroused.....
They leave you with the hole that they created.... a hole that can not possibly get fulfilled....
Thus many people wind up google'ing info about the favorite character... Or watching interviews.... Etc....
It's a desperate attempt to not be left hanging....
But the simple fact is that you will never get what you seek....
They basically take advantage of you... that's how I see it...
I try to keep myself busy and fulfilled so that I wont feel a need to watch a movie.......
Much success...
