Ebert liked
Knowing. But seriously Sheridan, you're putting a film you
haven't seen at #1?! DJaws hasn't eve added t to his list now he's seen it!

As if you're 'Best' list wasn't confused enough with
Terminator: Salvation and
Watchmen on it...

Just adding a few comments to my picks (8 of which are Original Movies, not adaptations, remakes or sequels, of which I'm quite proud!):
Best(500) Days of Summer - See my review
The Brothers Bloom - See my review
District 9 - It just feels so much like a defining 21st century movie. Like The Bourne Supremacy and Cloverfield before it, it took a fantastic premise and imbued it with an immediacy and a pathos the likes of which we haven't seen before.
The Fantastic Mr. Fox - Wes Anderson. Roald Dahl. Stop-Motion. If ever there was a winning formula...this film was everything I wanted to be and more!
Moon - Sam Rockwell nailed it in this movie. And it's such a simple premise so perfectly executed by Duncan Jones that it made me really excited to see what he does in the future.
A Serious Man - The Coen Brothers' Magnum Opus. And it just snuck in there. Quiet like. Accept the mystery.
Star Trek - Pyoom-pyoom-pyoom! Seriously, it's that simple.
UP - A heartbreaking, fun-filled, buddy comedy, road trip action-adventure movie about an old man with a floating house strapped to his back and a boy scout with daddy issues? I don't think-- SQUIRREL! --Pixar have made a movie that breaks the mould like this since waaaaay back when they made Wall-E.
Up in the Air - See my review
The Hangover -
WorstYear One - Tragic. See my review.
Bright Star - Good leads and a scene stealing performance by Paul Schneider, but this film was boring as hell, with a plot so slight it was anorexic.
Night at the Museum 2 - See my review.
X-Men Origins: Wolverine - As a comic book reader and a fan of good movies I'm offended by this garbage! (I haven't seen it but, according to The Boss, that's okay...Which also means Twaddington must put Moon on his 'Best' list nao

)
