Mooseboy: I've just finished watching the entire series start to end, and it was great. Every episode was awesome.
Except the last one.
*SPOILERS BE HERE*
The fact that they end it with "Oh, they're dead" really ruined it for me. Maybe its just because I don't believe in the afterlife or anything, but I found their time at the Dharma initiative was much more explantory, and everything after that kind of went down hill. The temple and all the other spiritual stuff? Meh, give me more sci-fi.
Mabey the creators were trying to achieve a balance between sci-fi and religion?
