One last thought on "The End" and I'm done. I was looking back through some of my old theories and such and came across this entry, and I couldn't help but think how much cooler (to me) a sci-fi ending to the show would have been.
I know most of you disagree, but I think right up until "Across The Sea," I was still expecting an ending like that. That change in expectations after AtS definitely contributed to my disappointment in the finale.
Makes me also realize just how wrong my predictions were about everything, especially in Seasons 4 & 5. *sigh*
