Knowing how "St Elsewher" ended (look it up if you don't) I'm a bit worried by Desmond referring to the island as a "snowglobe"...
Not sure about the reaction of "Henry" and the Others to the explosion - how much do they really know about the hatch? "Henry" lied to Locke about not pushing the button, so he obviously wanted to lull him into not doing so - do they want to bring down another plane??
Does anyone else find the structure a bit like a computer adventure game? There are different "locations", secret doors to be opened, objects to be picked up, etc. Characters hover over locations and pick objects up as if they are armed with cursors. The most contrived example of this was the hidden dynamite and Charlie knowing where it was.
The pantomime beard stuff is very odd and doesn't seem to fit. Why bother, if none of the others have disguises?
Amusing how, when the boat came, it was the three "alpha males" who stripped to the waist and leapt in the water! One for the laydees there. But I'm looking forward to seeing more of that Alex from the Others - hubba-dubba-DOO!
Is that the last we see of Michael and Walt, I wonder?... It would solve the "rapidly-ageing child actor" problem if so...
