Tv Season Info

When the action begins in season four, a year has passed and Arthur (Bradley James) is acting king while Uther (Anthony Head) remains in a state of depression. Morgana (Katie McGrath) aims to settle a score by summoning Callieach (Gemma Jones) to rip apart the fabric between the worlds of the living and dead, unleashing creatures that kill anyone whom they touch. Merlin (Colin Morgan) suspects someone close to Arthur is a traitor, and when he uses his alter-ego to show that magic is not a force of evil his plan backfires. Arthur takes the next step toward marriage with Gwen (Angel Coulby) but doubts her sincerity when he sees her kissing a revived Lancelot (Santiago Cabrera).

Critic Reviews for Merlin: Season 4

All Critics (5)

There were a few cool bits in this episode. Gaius convincing Arthur to take Merlin more seriously is a moment I did not expect but after four years I it welcomed it enthusiastically.

It does pleasantly expand on the universe of the series.

October 17, 2018 | Rating: 3.5/5 | Full Review…

As long as you don't expect it to be pure drama, high brow fantasy or a necessarily accurate retelling of Arthurian legend, there's plenty to enjoy.

It's a pity John Hurt's dragon has little to do, but the addition of more knights and murkier tales makes up for the loss.

Morgana's to blame for the mayhem. I knew that girl was trouble; something about her flashing yellow eyes, her long black hoodie and the way she can send a knight in full armour flying just by waving an arm.
