Trailer of season 1 of British TV series, Merlin
Merlin is a British television series that aired from 2008 to 2012, focusing on the origins of two legendary characters Merlin and Arthur, showing the adventures of two people in their youth. Many famous actors have appeared on Merlin, and the series has had funny, magical moments that viewers have to watch again and again.
While it tends to lean towards monster plots, the characters and their relationship with each other really make Merlin special. Merlin's progression from apprentice to powerful witch, Arthur's transformation from prince to king, and Morgana's turn into villain are satisfyingly impressive character "arcs" that last throughout. 5 seasons of the series.
