And the Oscar goes to...

The 3 best:

Avatar

Sandra Bullock

George Clooney

The 3 worst:

All forró composers ...

Britney Spears

Chris Brown

I loved Avatar, but as I haven't seen The Hurt Locker yet, I may change my mind after seeing it.
George Clooney doesn't need to act well, in my point of view. Just seeing him on the screen is enough!
It was hard to list the 3 worst, then I chose forró because of the lyrics (if it's possible to use this word in that case), Britney Spears and Chris Brown, because of their attitudes.

See you,
Bia
