It's nice that you like this movie, and thanks for sharing your viewpoints because I can now see more clearly why you like it. I still don't think it's a good movie though. Nice discussion anyways.
I mentioned this before, but one of the biggest reasons I think helped me liking the movie is that I went in with my expectations extremely low, I wasn't expecting the movie to be good, I meam it is with Justin Timberlake after all.
On top of that, there is this strange phenomenon that I don't know if others experience it too, that when I watch a movie without knowing anything about it, I mean not even a trailer, or someone mentioning something about it, and then the movie happens to be good, it makes it even more good because of the element of surprise.
That said, the biggest thing that got me was the excellent script, I mean the writing, the plotline, the story, and their overall argument, was really touching because it is a very conscious message that you may as well call the movie: "Based on real life."
It covers some of the most important points that need to get across our society in general. These are the key things that matter.
I've seen other highly fictional movies trying to accomplish the same result, like "Click" with Adam Sandler, or "Elysium" with Matt Damon, but those movies fail in addressing the main issues within people's fundamental way of acting.
Instead they only touch the superficial layer. In the case of "Elysium: it blames politics, and macroeconomics. In the case of "Click", it may go deeper by blaming the narrative of society affecting our view of the world.
However "In Time" even though it also touches on those things,
even bringing up the federal reserve at the end,
simply hits home by going directly to the route cause which is human behavior, stupidity, getting caught up, and never looking at the big picture.
If you like to read quotes from famous celebrities of the past, mostly scientists, painters, musicians, and authors in the like of Oscar Wilde, Honoré De Balzac, Albert Einstein, William Shakespeare, Nicola Tesla, Victor Hugo, Blaise Pascal, Jean-Paul Sartre, Niels Bohr, Johann Goethe, etc., you'll soon find they all touched on the subject matter surrounding this movie.
I feel the movie could easily be seen as highly artistic in the sense that the whole movie plot is purposely set as far as possible to actual reality, making it look like one of the biggest lies ever told.
In other words one can rapidly realize how impossible that kind of setting could exist in real life, which is what makes it fascinating because despite of that being the case, it is one of the most accurate description of the real world we live in.
I would say they perfectly nail Pablo Piccaso's saying:
"Art is a lie that makes us realize truth".
When I finished the movie I wanted to stand up, and give a big round of applause to the writters just for that alone.
In hindsight, I couldn't expect less from the guy behind The Truman Show. A truly magnificent movie, I highly recommend it to everyone.
