There Will Be Blood
Director Paul Thomas Anderson has done great things with There Will Be Blood. After my first viewing, I believe the film to be about runaway ambition at the cost of anything and anyone around you - but I could be wrong. At any rate, I plan to watch it again, and I can only hope that Daniel Day Lewis indeed receives the Oscar for Best Actor.
There were scenes in this film which tightened my innards, making me writhe with discomfort. There's one scene, particularly, where Lewis' character forces his son to drink a glass of of goat's milk mixed with a heavy dose of whiskey to calm the child down. It's a fixed shot held for what feels too long - not in the poor editing sense, but rather long enough to force the audience into sharing the discomfort.
5/5, and I certainly plan to add this to my collection when it releases on DVD.
P.S. The sound editing was excellent - every little scuff and scratch, match strike, and tool click was audible just the right way. No wonder that's another of the 8 Oscars for which it's nominated.
