The other reason I watch it is really to see the production value increase over time. During the first couple seasons, they had to keep using the same sets, scenery and props over and over. As it became more popular, they had more money to spend, and suddenly there were new locations, new sets, and much improved special effects.
The TV series is still much better than "Camelot" though. "Camelot" had a great first episode.. and the rest was rubbish. Everyone really needs to stop rebooting the King Arthur and Robin Hood franchises.. just leave them alone for a couple decades for heavens sake.
So anyways, I was watching "The Wicked Day" the other day and it pissed me off a little. In the beginning, Merlin had plenty of opportunities to expose Morgana, but I can understand that the writers wanted him to foolish, young, and naive. But now he's supposed to be smarter, more clever dealing with Morgana's tricks, and you'd figure he would clue in now that they're 4 whole seasons in. It's just plain bad writing, and it would have made much more common sense if the episode happened like this:
Plus, he's supposed to be able to "sense magic" in the first place.. he just gave a long speech about magic being "all around them". And yet, he doesn't even notice evil magic charms and auras on the King.
