Look at it this way...

From the documentative mode of filmmaking to Hollywood narrative, film has come a long way and has a long way still to go. New techno-computer advancements are playing not only a catalist role but a producing role in today's filmmaking.

Gone are the days when reality was real, atleast in front of the camera; understanding ofcourse that even that reality was a constructed one unless it be a documentary. Before film consisted of capturing the moving image, narrative and building an institution that existed entirely around audience entertainment. Digital image production has led to the production of virtually created characters and locations, making the very world of the movie non-diegetic. Science fiction movies and digital animation have experienced much with digital image production. It is a great way of filmmaking but then you wonder, where does the real world exist when everything is computer produced? When even constructed reality is re-constructed?

But look at it this way, we go to cinema for escapism, entertainment and to challenge our existing ideologies. That is exactly what cinema does for us today, only we don't merely sit and watch, actively engaging in the world of the film, but we become inhabitants of that world. We form part of the narrative, we go to the lcations and we go out of the cinema having experienced the movie as opposed to just watched it.
