I'm super excited that this show has generated so much passionate discussion. Please remember that you should stick to posting what you think of the finale and the show, and refrain from commenting on how you can't believe other people loved/hated the finale or speculating on why other people loved/hated it -- those latter two are boards-on-boards.
"I loved X and Y!" or "I was disappointed in X and Y!" are both great.
"I don't know what all of you who wanted X were expecting" or "Some people are too nitpick" or "I can't believe so many of you liked the ending" are all boards-on-boards, and if you post it, your post will be edited or deleted.
PM me if you have questions.
