I loved Merlin and Arthur, their growing bond. But I hated the end. Could have ended differently or come up with a new season or a movie for its closure. The ending ruined all the experience of 5 seasons.
All I can think off to get a good feeling of the ending is that...... Merlin is still alive and around the island after 1000 years, coz Arthur takes rebirths and in every birth Merlin stands tall beside him...And now he is again walking near the island as he is waiting for Arthur's another birth. ๐ญ
