Overview: The young wizard struggles to protect Prince Arthur in the perilous world of Camelot. While battling deadly assassins mystical monsters and the most powerful sorcerers Camelot has ever seen Merlin now has to face his toughest challenge yet when Morgana's blind determination puts at risk Arthur's future as well as the very balance of the world.

DVD Verdict: For those not in the know, this show is very different from any of the past Merlin's and King Arthur's that have been done. This is when they are all very young men and how Merlin grows into becoming a great wizard. I love the banter between Merlin and King Arthur. The acting is great and the stories are very well written.

Indeed, it is a clean program that children can watch. It is refreshing to see a program where you don't have to deal with foul language and sex. I would recommend this show to anyone who enjoys great acting, magic, and humor.

So, that intro aside, the development of the characters has progressed over the seasons and they are more likeable now than ever. I don't like to think of this series ending after the fifth one, but it is something to add to the 'All good things must eventually come to and end' folder, for sure.

I thought they actually did a good job with the character arcs. Arthur and Morgana for instance: In that first season I would not have thought it possible Morgana would turn into this evil villain she eventually becomes. And Merlin gains more and more ability so gradually I hardly noticed it happening. I wasn't expecting Merlin's elderly alter-ego to become a regular thing either. By the end of the fourth season it was just seemed like it fit perfectly.

Some famously named knights, Lancelot for instance, make appearances early on but leave upon realizing Camelot isn't ready for them. In one episode they even find a long abandoned castle with round table in it. And over several episodes in different seasons Merlin manages to work in the sword in the stone part of the legend.
