Merlin Portrayal
I just finished watching this show on HULU with my wife and I am not sure if this topic has been discussed yet or not so I apologize if it already has.
I feel that the way they portrayed Merlin in this series was the best adaptation of the character yet! I love the fact that he is not portrayed as an elderly bearded guy with almost supreme magical power. In this, he is "young", struggling with his powers, and tormented by personal demons that they don't really delve into enough.
I would literally watch an entire show based on this character alone with the Arthur legend as sort of a side note. IMO, the best part of the entire way they portray the character is the way he is sort of creating the legend as it is happening. He had a horrible experience with getting the sword for Arthur that ended in a girls death, and turned that into the legend of the Lady of the Lake. I am not sure exactly how he was involved with the Sword of Mars, but they alluded to the fact that he was involved with the creation of that legend also.
Anyway, I thoroughly enjoyed the unique portrayal of Merlin in this show and hope that another show/movie uses it as a model in the future.
