Pretty good season finale, although I couldn't help being a bit disappointed that it followed the blueprint of the first season's finale (more people kidnapped, few questions answered, cliff hanger). And I'm really not liking this "everyone knows everyone" bullshit coincidences concerning half the cast randomly meeting each other before the plane ride. Sigh
but uh..
-Fuck Michael. I know he loves his son and all but there comes a point where you have to man up.
-What happened to Siyad (mupepe

)
-The whole Penny-finding-the-island thing seems way too coincidental to me. Pretty weak cliff hanger imo
-Henry/the Others=cool. I want to know more about them. "We're the good guys"? so who are the bad guys
-and why do they want Sawyer of all people ha
-How is Mr. Eko still alive

-I guessed awhile ago that the island was some human control experiment, and for awhile I thought I was right (along with Locke)...but now I dunno. On one hand it does seem like some type of experiment WAS going on (capsules with the notebooks being piled up, unread for instance) but then again, not pushing the button does seem to have a consequence. Also Henry must have been lying when he said he didn't push the button right? And in that sense, perhaps he didn't want Locke to continue pushing it so something could happen. Now people know where the island is located...so more teams will be on their way.
-why did the others let Walt go?
