It lacks Narnia's Lion giving an a award to Tom or something more absurd. The queen faults on quality of character designs, besides this happy ending was far away from the sacrifice style of the whole series.
Finally as others says, they tried to solve everything so quickly, John Pope breaks bad in the middle of the season took many episodes to explore the issue that he became to give him an end like that. Ben's spikes have to be affected in some way, with espheni death as dominoes effect. Isabella was relegated to have no impact on love's story where she was enrolled, so I feel that there is much things unresolved for a finale episode.
