A Clockwork Orange

I recently watch Clockwork Orange which I have mixed opinions on. I think it is unnecessarily explicit but I like the story line and how Alex is 'cured' psychologically aswell as the memorable last line

Although I dislike the context of this next explicit scene, I like how the song 'Singing in the Rain' is used for bold contrast as it is usually a nice, happy song whereas Alex sings it whilst breaking and entering and assualting a couple. I also like how it returns further in on the film to haunt the old man when Alex returns to this house and is punished by the old man he assaulted years before.
