ah yes, the great wizard Merlin. i actually own this one. the only thing i wish they did better on it was the transition from scene to scene. the transitions were made for the tv, unfortunately, but in DVD form it makes it a bit odd.
i love Sam Neill, he is an excellent actor, and i must say, they did good to make him Merlin. he does it well. even i the sequel "Merlin's Apprentice" he does great acting.
and the actors who play the fair people are seem quite made for their parts.
