I finally just watched the finale, I've been putting it off probably cause I either didn't want it to end or was afraid it'd suck, but I have to say I'm incredibly impressed. From an emotional point of view I hate how it is confirmed that they all die sooner or later (which is a given anyway cause we all die but still), but from a storyline-perspective it couldn't have ended any better. A lot is answered while some mysteries remain, which is good. I've always loved Lost, but there were times (season 5) where they totally lost me, so seeing an ending like this makes it all the more impressive.
