I would like to point out that while I do seem to be defending the ending (mostly the idiocy of thinking Lin's sacrifice was cheapened), it really was resolved far too quickly. Even if they'd just cut it off at her Avatar Stating, it would have been much better than the super crammed ending they did make.
And yes, they probably didn't know they had a second season when they planned it. Edit it after the fact or end it on a cliffhanger if you have to, I don't care. The last few minutes were just bad.
