Arthur kills Mordred but is wounded and rescued by Merlin, who reveals that he is a wizard. Arthur is initially hostile but, advised by Gaius, allows Merlin to take him to the healing lake of Avalon. On the journey, Arthur comes to appreciate everything Merlin has ever done for him and eyes him with a new respect, even softening in his attitude to magic, but Morgana is pursuing them.

Finally ... we all get to experience the magic.
30 April 2015 | by A_Different_DrummerSee all my reviews

Be honest, I am a cynical, jaded and hardened reviewer here, but this two part ending nonetheless made me sad.

Many of the reviews of this finale also made be sad, but for entirely different reasons. So I will address the following points:

* regardless of the fact that there are many different version of the legend, what they all have in common is that it is at its core a tragedy, possibly one of the oldest and most iconic tragedies of all time

* let's show some empathy for the writing team that attempted to turn this tragedy into a multi-year series. True they cut some corners here and there, but, by and large, taken as a whole, this is one of the best written and most entrancing series I have encountered.

* within the confines of the comments above, the finale was not inappropriate, it was the only appropriate ending. Many loose ends were tied up. They even (clever monkeys!) sort of gave themselves an opening for a sequel which, the blogs tell me, will never be green-lighted. Pity.

* and let's talk about the acting. Morgan evolves from a clownish second banana to one of the most dramatic characters I have ever seen, and James matches him scene for scene. This is astonishing.

* even better, Katie McGrath maintains her title as the most photogenic villain I've encountered in many a year.

The 2-part finale goes from wide-scale conflict in part one to personal conflict in part two. It holds the attention. It speaks to the viewer. The acting is to die for.

In short it is indeed magical.
