Which movie do you like the most and why do you like it?
The movie that I like the most is Matrix. I like it from both cinematic and subject point of view. Cinematically, it was a great movie in its time. It had great special effects and computer graphics (CG) was used extensively in it. The creators even introduced new ideas in filming the scenes like using multiple cameras at different angles to create some of the mind-blowing action scenes. The cast also did a great job. I've watched some behind the scenes and noticed how much effort all of them had put to create the best and believable scenes. 
But the most interesting part of the Matrix movie for me is its subject. It is about a virtual world created and controlled by computers which simulates the life and creates the illusionary perception for the humans that they are really living, but in fact it is only their minds that are the habitants of this world and their real bodies are imprisoned in incubators and are being utilized at energy sources by the computers. I really like the idea and also how one can generalize it to the real world that we are living in. What if this world and the life on it is just a projection or a shadow of a higher form of life, like a two-dimensional shadow of a three-dimensional object in space.
