I've heard if you look hard enough on the web you'll find all the spoilers or at least most of them...I want to be surprised so I'll avoid all that.
I just finished season 5 this past week and I can't tell you how happy I am that we are past the living in the 70's show staring Sawyer and Juliet. My wife agreed with me that was a serious low point in season 5, except for a few characters no one had anything to do in the middle of the season. We were left with Sawyer trying to hold onto his live in Dharmaville and it slowed the overall story down. It wasn't till we got past that crap the story picked up again. This last season should be nothing but answernig questions otherwise they'll be forced to answer everything in a two hour finale and that didn't work out well for the X-Files, it won't work for Lost either.
Though I agree this is the best show on TV right now I would be hard pressed to say it changed TV...hell, Firefly was doing the flashback episodes before Lost was even someone's idea. But that is a matter of opinion of course.











Best.Show.Ever.PERIOD.
No if's, and's or but's.....Nothing has changed TV more then Lost in the pas 2 decades (so yes, Lost is better then BSG in my view).
Cannot wait for this final season.
