After watching the Season Four finale episode, I just wanted to post here and let you know that I think you delivered a sterling performance!

The Sun character has always been among my favorites; we have seen Sun grow from the slightly timid, repressed woman she once was into the multi-layered character we know today. Your acting, moreso than the dialogue, is what captures this growth.

I was not impressed with the Season Four finale at all. I have been a LOST fan since day one, and I feel let down by many aspects of the show as it evolves... but you really are the one shining beacon in this finale. You have an incredible range; it's easy to see now why you are such a successful actress in Korea.

I FELT Sun's anguish as the freighter exploded and Jin (apparently) died. You captured the emotional temperature of the audience brilliantly. And then in the scene between Sun and Charles Widmore, you once again demonstraded your exceptional range by playing Sun so.... coldly. Detached. Calculating. I was duly impressed. :)

Kudos to you for a wonderful performance.
