Actually the reception to that is warmer than you seem to think and it certainly does a lot better than dangling the promise of a 2nd season to the viewers and then not giving them anything. Trust me.

FMA had this same issue but unlike HotD the makers of the anime went with making an alternative ending and it worked out fine.
