User blog comment:LokiIsAwesome/Agravaine and a few other Series 4 characters.../@comment-4135736-20120813205522

I agree about Agravaine but I don't think he was a pointless character, he did have the potential to be a better character, but rather than make him an interesting and complex character like Uther, the producers just made him into a smirking and one-dimentional character. And yes, making him another enemy within the walls of Camelot was another bad choice, but I don't think Series 4 was the worst season (there were a few things I liked, especially the improvement of Morgana's character as she smirked less and showed more depth inside her, that is how she should have been in Series 3) that goes to Series 2 with all those random filler episodes (Series 3 is my favourite season, despite my disappointment over Morgana).

I especially agree about the Cailleach and the Lamia. I just couldn't understand the Cailleach, she had no character development at all - why was she always sad, why did she tell Morgana about Emrys yet hesitate to sacrifice Merlin, and most of all why did she laugh when Arthur told her that innocent people were dying. As for the Lamia, she was another bland character (how come Arthur was able to kill her when Merlin fail to defeat her with his own magic), but the episode she was in was pathetic, just an excuse to show courage inside Gwen which could have been shown in another way.

Anyway, I am giving Series 5 a chance to improve from Series 4, I am glad Mordred is coming back, as long as they don't make him another version of Agravaine.
