Well for once here's a list i really can't do- i've only seen 3 films in your 10 list, WPQX. The Weeping Meadow was about the only film i got to see in 2 months in Portugal, i managed a little spurt when briefly back in UK (living in a caravan), and now here in France they're well behind at cinemas and dvd rental.

I liked Sin City; despite its being so typically + relentlessly violent, it did seem to offer something new, struck me almost as an admittedly inferior Kiss me Deadly for the 21st century. I didn't like From Dusk till Dawn at all- silly childish nonsense. El Mariachi had promised a bit better but then he got too close to Tarantino, i reckon. QT's little section in Sin City is the weakest part of the film! 

I've got a lot to look forward to:

Brokeback Mountain
A History of Violence 
L'Enfant
Hidden
Serenity
The World
The Wayward Cloud
King Kong
Charlie and the Chocolate Factory
Curse of the Were-rabbit
Three Burials
The Squid and the Whale
Munich
Boken Flowers
Good Night and Good Luck
The New World (i saw a clip 2 months back that immediately struck me as a copy of Sansho the Bailiff, then remembered Malick is a Mizo fan and did a stage version of the film)
Kiss Kiss Bang Bang
Capote
Where the Truth Lies
The Constant Gardener
Syriana
Three Times

rating some first released in 2005 i have seen:

Sin City 8

The Beat that my Heart Skipped 7 (can't see what all the fuss was about- i'd heard it was something very original)
War of the Worlds 7
The Descent 7
Batman Begins 7

March of the Penguins 6 (some lovely shots of landscapes, but in the French version i saw here the voice-over and music were awful, irritating, completely undermine the excellent cinematography)

i may have been slightly generous in my markings.

From 2004 but only here in 05 I most enjoyed The Life Aquatic + The Weeping Meadow, (minor Angelopoulos but still a major film Bitish critic Jonathon Romney said, and he's probably right, though i think the standing compared to other Angelopoulos will only be clear with the full trilogy.) 

As with earlier stuff (overrated i think) by Wes Anderson, The Life Aquatic hardly hides its eccentricities, but this time it does seem original, a rare adventure indeed!
