Some of these are a little more than 5 years, some aren't:
Nightcrawlers (seconding that here)
Zodiac - a perfectly done historical suspense film that does something only the very rarest films do - actually give me the creeps. I loved it. I've seen it twice and will definitely watch again every few years.
Adam's Apples (it's Danish so you would have to watch subtitles, but it's unbelievably original and frickin' hilarious)
