right down to the flipping a switch style character development. Morgana is good, then evil and never looks back. And now gwen was broken, but she doesn't seem conflicted or confused, just completely evil now as well.

Like why couldn't they make Gwen a surprise double agent. Or have Merlin reveal his magic to her before and explore that conflict, loyalty to her friend vs her husband etc. God they have so many options and chose to just recycle story lines.
