I recently re-watched There Will Be Blood for like the 20th time.
Daniel Day-Lewis, as always, is incredible. The score is by Radiohead guitarist Jonny Greenwood, and it's also amazing. And while I wouldn't say it's got a whole lot of anything that's virtuous, lovely, of good report, or praiseworthy (there's no big cuss words or nudity at all) it's at least a good illustration of what not to do with letting yourself get consumed with money and success.
These are two of the best scenes. The intro is magnetic, there is no dialogue for the first 20 minutes but you're fixated anyway. The fire scene is great too. https://www.youtube.com/watch?v=T3O-OEem3XM
