Hey Mike,
Thanks for starting the thread, I appreciate it. Just to avoid defending a position that I haven't taken. Here is what I meant in my review about the mirror smashing:
a) I did not "feel" his rage had been built up to as well as it could have. As in his behaviour in the episode did not make me see his rage as a natural progression and so it felt very sudden. And that suddenness took away from the moment for me.
That is entirely a TV production criticism. Not a character one.
b) I have no problem believing that Jack would get that angry. That did not seem out of character.
What did not help was his lack of curiosity in the lighthouse and how the mirror might work. But Jack has shown a lack of interest in the everything from the hatch, to the barracks to black smoke floating in front of him. So again I don't have a problem with his behaviour except in the wider context of the way "Lost" makes its characters look dim sometimes.
c) When I liken Jack smashing his father's coffin to smashing the mirrors I am saying something specific. Which is that losing one's father is something any viewer can relate to and so Jack smashing up the coffin had an emotional impact. When combined with being lost on an island and chasing your Dad's ghost around I thought it was a compelling piece of drama.
When you are trying to demonstrate how someone feels after leaving that island, losing their fiancée, becoming an addict, returning to the island, travelling through time, detonating a nuclear bomb, being beaten at the Temple, trekking across the island and then finding out someone has been spying on you (deep breath)...your emotional state is no longer so clear or relatable. Therefore to me, this had far less impact as a dramatic moment of TV.
I was not suggesting that Jack, the character, was behaving in an implausible or uninteresting manner.
Ok. Now that that's out of the way. Mike, can you expand on your theory about why this is a big deal for Jack. And how it will lead to him confronting Jacob in some way...
