I watched the first three episodes again, several times. All these nay sayers must have been tuned outeven before the first episode, because they just don't seem to be backing anything up with much of anything.
While not everything is explained (if it was, it would be better off a miniseries not a weekly show), it does set everything up in such a way that makes JJ Abrams look brilliant.
Someone addressed the issue of the plane crash looking fake without realism... I called a few people talked to some others and checked with other boards; It's morte plausable than people think; theres TWO important factors everyone seems to leave out...
1) you can never fully predict what happens in any given crash. while there are some simple "predictable" physics involved (ie; plane falls apart, plane will go down), you can't possibly figure it out.
2) Theres a STORNG indication that the air "event", the decent, and the crash MAY have a supernatural or "controled" aspect to it. In the words of my friend, "Perhaps the island has a defense to it... it clearly has a dead zone to it".
Which makes sense. Obviously, if they took the dinosaurs route, it would get old fast - and the polar bear indicated there was a sort of natural "but unatural" element to it.
Of course, everything will be explained as the season(s) progress, but if it is a "Splicing colony", I'll scream.
Locke, of course, will reveail a bit too much in episode 4.
