2007 was the best year for music and film in recent memory. In 2007, these came out:
No Country For Old Men
There Will Be Blood
The King Of Kong: A Fistful Of Quarters
The Assassination Of Jesse James By The Coward Robert Ford
The Bourne Ultimatum
Spoon - Ga Ga Ga Ga Ga
Radiohead - In Rainbows
Battles - Mirrored
The Austerity Program - Black Madonna
Yea Big & Kid Static - s/t
PJ Harvey - White Chalk
Wu-tang Clan - 8 Diagrams
Nina Nastasia & Jim White - You Follow Me
Dälek - Abandoned Language
Yeasayer - All Hour Cymbals
Plus on TV, there were the premieres of Mad Men (thus paving the way for Breaking Bad and the makeover of AMC as a powerhouse of critically-acclaimed drama series), Pushing Daisies (which had characters doing musical numbers well before Glee) and Burn Notice (the best post-24 action series and the template for a new genre: the "expert helps out regular people" show).
I don't have top ten from any other year that can touch those in terms of quality, diversity, or cultural significance. And I doubt we'll see another year like this anytime soon.
This year, for example, I can't even scrape together a top 5 of movies I've seen so far. I liked Inception and... what else has there been? Music? I'd rather not talk about it. This decade is not off to the most promising start.
But maybe I'm holding it to too high a standard. Not every year can be like 2007. And maybe I'm even wrong about that. Has there been a better year that I'm totally forgetting?
