Matthew Fox has SOOOO impressed me more and more on "Lost!" In last season's finale, his scene with Benjamin, during which he hears gunshots over the walkie-talkie, is incredible. I love Fox's performance here. Any actor could have simply flipped out or gone just 'violent.' Instead, Fox offered a layered, complicated moment: like aggression that's filtered through desperation and heartache, reaching a breaking point. It gave me chills.
Then, this season already, he's continued to convince me he's more than a TV star; he's an actor's actor, as well!
