We finally watched the season finally last night. We feel resolved by the way they ended it. I'd rather it end like this then try to come back and not give any closure. We didn't think they'd be able to tie things up but they did pretty good.
I thought they tied up things well also. Now that that's been done, they may not want to be picked up by another network. If they'd continued fighting, like a revolution, then they could have gone on for longer.
