I would say that the movie is really a gem of an art piece. The use of excellent imagery coupled with pretty out-of-the-place background score tells us about the uniqueness of this movie. Stanley Kubrick has really applied a lot of thought into this.
The director wants the audience to feel something as bad not because he is showing it as bad but because it really is bad. The background music accompanying the ultra violent scenes is comical, and not dramatic or anything else that is commonly associated with such scenes. This gives the viewer an opportunity to feel the bitterness not because the music hints so but because he himself feels so. Viewer's emotions should arise irrespective of what the director is trying to show, and this is one of the greatest successes of the movie.
Another glorifying feature is the central idea of the movie. If a human is striped of the choice to choose from good and evil, he no longer remains a human, he becomes a clockwork. When Alex is brain-washed and "programmed" to choose only good, he wasn't accepted by the society and this shows the irony in the objectives of the British Government. The word Orange from the title presumably comes from the word "Ourange" that loosely means man. And hence the title is so appropriate to the movie.
The artificiality in dialogues and sets give the movie a unique feature and enhance the grip on it. This also means that the viewer has to get more involved. This is definitely one of the best technically shot movies, another masterpiece of Kubrick like the Space Oddessey.
For the uninitiated, set in near future Britain, the movie shows Malcom MacDowell as the head of a group of youngsters involved in sexual violence. Turn of the events leave the protagonist in the hands of the police. Worried by the growing number of prisoners the British Government devises a method of "programming" them so that they always choose the good. Alex is chosen as one of those on which the new system is to be tested. The rest unfolds as a saga of the very human characteristic.
Lastly, I would like to say that you may be compelled to leave the movie in between, but if you are watching it for art and cinematic experience, I recommend you to sit through.
