User blog comment:LokiIsAwesome/Agravaine and a few other Series 4 characters.../@comment-3012002-20120813102330/@comment-5139779-20120813124303

Completely agree with you there Fimber, a one-dimensional villain in the first place is disheartening but having one in 13 consecutive episodes just really pisses you off. The only reasons Agravaine has are only implications.

I furthermore agree with Series 4 seeming like somewhat of a standalone season as they forgot elements such as Merlin's ability to sense magical objects and the Great Purge I don't think was even referenced once directly. So it pretty much sums up that they put a little too much effort in making Series 4 good that they forgot about everything that had previously happened. One thing I was glad about Series 4, was that we got quite a few references to Odin, not an appearance, but it's better than nothing.
