Honest criticism,
This series is most enjoyable for people who are looking for a common fantasy series...
The series' plot pacing is too slow, the characters are not introduced properly, it's like watching a copycat of the 1st season of American Gods... The fight choreography isn't great... Iris is just "evil" for some unknown reason, and the main characters are extremely annoying (honestly, Arthur and nimuë are just so annoying... Gawain, Merlin, Pym, or the weeping monk are better characters)...
Also the way they sneak through the enemies is just too stupid...
The way they reveal the true identity of some of the characters was awesome though... And Gustaf Skarsgard as a drunkard Merlin was just perfect...
Overall the series was enjoyable...
This is one of the few series where the side stories are more entertaining than the main arc...
